13.01.2025: Unterstützung für geplantes Exzellenzcluster: Physiker Samir Lounis tritt Professur an der MLU an
Prof. Dr. Samir Lounis ist seit Januar 2025 neuer Professor für Quantentheorie der Festkörper an der Martin-Luther-Universität Halle-Wittenberg (MLU). Lounis forscht zu Quantenphänomenen in Materialien, die für die nächste Generation der Informationstechnologie und Elektronik gebraucht werden. In seiner Arbeit nutzt der erfahrene Forscher komplexe Berechnungen und Simulationen, um die Eigenschaften dieser Materialien vorherzusagen. Mit der Berufung von Samir Lounis baut die MLU ihre wissenschaftliche Expertise im Bereich der Festkörperphysik weiter aus und besetzt eine wichtige Position für das geplante Exzellenzcluster "Center for Chiral Electronics".
Auf der Nanoebene verhalten sich Materialien anders, als man es im Alltag erwarten würde. In diesem Bereich tauchen sogenannte Quantenphänomene auf, die ungewöhnliche Eigenschaften hervorrufen. "Elektronen sind maßgeblich für diese Phänomene verantwortlich. Ich möchte verstehen, wie sich Elektronen in verschiedenen Materialien verhalten und welche Effekte man dabei beobachten kann", sagt Samir Lounis. Dazu gehört zum Beispiel der Spin von Elektronen, eine Art Eigendrehimpuls, der ein magnetisches Moment bewirkt. In der Spintronik erforscht man, wie man den Spin zusätzlich zur Ladung als Informationsträger nutzen kann. Eine weitere Eigenschaft ist die sogenannte Supraleitung, bei der Elektronen nahezu widerstandslos durch Materialien fließen. "Derartige Effekte spielen eine große Rolle für die nächste Generation der Elektronik. Meine Kernkompetenz liegt in der Beschreibung und Vorhersage derartiger Eigenschaften", sagt Lounis.
Sein Know-how bringt der Forscher in verschiedene Forschungsverbünde der MLU ein: Dazu gehört vor allem das geplante "Center for Chiral Electronics", mit dem sich die MLU gemeinsam mit der Freien Universität Berlin, der Universität Regensburg und dem Max-Planck-Institut für Mikrostrukturphysik in Halle um eine Förderung in der aktuellen Runde der Exzellenzstrategie bewirbt. Weiterhin wird sich Lounis in dem Sonderforschungsbereich SFB/TRR 227 "Ultraschnelle Spindymaik" engagieren, den die MLU gemeinsam mit der Freien Universität Berlin betreibt. "Die Universität Halle verfügt über eine weltweit anerkannte Expertise im Bereich der Festkörperphysik. Ich freue mich, die exzellente Forschung hier künftig mitzugestalten und ausbauen zu können", sagt Lounis.
Samir Lounis ist Autor und Co-Autor von mehr als 130 wissenschaftlichen Publikationen, mehrere davon hat er in renommierten Fachzeitschriften wie "Science", "Science Advances" und "Nature Physics" veröffentlicht. Auch beim Einwerben hochrangiger Drittmittelprojekte ist Lounis äußerst erfolgreich: 2016 erhielt er einen der extrem begehrten ERC Consolidator Grants des Europäischen Forschungsrats ERC in Höhe von rund zwei Millionen Euro.
Lounis wurde 1977 in Algerien geboren. Von 1995 bis 2002 studierte er Physik an der Mouloud Mammeri University in Algerien und am Straßburger Institut für Materialphysik und Chemie des Centre national de la recherche scientifique (CNRS) in Frankreich. Anschließend forschte er am Forschungszentrum Jülich, 2007 folgte die Promotion an der RWTH Aachen. Nach einem einjährigen Forschungsstipendium an der University of California at Irvine, gefördert von der Alexander von Humboldt-Stiftung, wechselte der Physiker als Forschungsgruppenleiter zurück nach Jülich. Von 2015 bis 2020 absolvierte er eine Juniorprofessur an der RWTH Aachen. Anschließend war er bis zuletzt gemeinsamer Professor des Forschungszentrums Jülich und der Universität Duisburg-Essen.
17.12.2024: Current generated by the quantum Hall effect has additional magnetic properties
The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of atoms. This has been demonstrated by the calculations of a team from Martin Luther University Halle-Wittenberg (MLU) which were published in the journal "Physical Review Letters". These results can potentially be used to develop new types of inexpensive and energy-efficient devices.
Electricity flows through all types of electronic devices, be it mobile phones or computers. However, this generates heat, which means that energy is lost. It also means that conventional computer chips cannot be infinitely scaled down. In the field of spin-orbitronics, researchers are looking for alternatives for storing and processing information without the loss of energy. The basic idea is to utilise not only an electron’s charge, but also its spin and orbital moment when processing information. Spin is the intrinsic angular momentum of an electron, and the orbital moment arises from the motion of the electrons around atomic nuclei. "Combining both effects would allow us to design new devices that are more powerful and efficient," says physicist Professor Ingrid Mertig at MLU.
The basis for the new study is the quantum Hall effect. Klaus von Klitzing received the Nobel Prize in Physics in 1985 for its detection. The effect is observed when electrons are subjected to a very strong magnetic field at extremely low temperatures. "The quantum Hall effect is special because the electric currents that are generated only flow at the edges of a sample. Furthermore, the associated electrical resistance can only take on specific values," explains Dr Börge Göbel. Even though scientists have been aware of the effect for several decades, the team’s calculations have provided a new insight: the edge currents also have magnetic properties due to the orbital moment of the electrons. "In the future, they could be used to transport additional information and to operate electrical devices more efficiently," says Göbel. Remarkably, the new effect occurs in addition to the quantum Hall effect and is not tied to rare and expensive materials, as is often the case in spintronics.
Göbel and Mertig are already continuing their research as part of the international research project "Orbital Engineering for Innovative Electronics" (Obelix), which is funded by the European Innovation Council’s "Pathfinder" programme. The goal is to find new, marketable technologies. To this end, Mertig and Göbel are collaborating with research institutions in Germany, France and Sweden.
Mertig and Göbel are also contributing their expertise in the field of spin-orbitronics by participating in the planned "Center for Chiral Electronics" for which MLU is applying for Excellence Strategy funding together with the Freie Universität Berlin and the University of Regensburg. The Max Planck Institute of Microstructure Physics in Halle is also involved.

04.01.2022: Der Forschungsschwerpunkt „Nanostrukturierte Materialien“: Ein Erfolgsprojekt des Europäischen Fonds für regionale Entwicklung (EFRE)
An der Martin-Luther-Universität Halle-Wittenberg finanziert der Europäische Fonds für regionale Entwicklung (EFRE) die Forschungsarbeitsplätze von 14 promovierten Wissenschaftlern aus Physik und Chemie im Rahmen des Forschungsschwerpunkts „Nanostrukturierte Materialien“. Die Förderung mit rund 5,4 Millionen Euro EU-Mitteln ist eine lohnende Investition: Zahlreiche Projekte, an denen hier auf der Ebene der atomaren Organisation von Materialien geforscht wird, können zu Anwendungen führen, die unsere Zukunft verändern. Winzige, nach Bedarf rekonfigurierbare Dioden machen Schaltkreise effizienter und flexibler im Vergleich zu existierenden Bauelementen. Nanopartikel helfen dabei, dass sich millimetergroße Löcher im Lack von Flugzeugen oder Autos wie von Zauberhand selbst schließen. Der EFRE investiert im Rahmen des Förderprogramms Sachsen-Anhalt WISSENSCHAFT (Schwerpunkte) in diese faszinierende Forschung, um Kompetenzzentren im Bereich Forschung auszubauen, insbesondere solche von europäischem Interesse. Diese hohe Messlatte wird von den Forschern in Halle in vollem Umfang erfüllt.
Der Forschungsschwerpunkt „Nanostrukturierte Materialien“ besteht bereits seit dem Jahr 2004 und leistet einen wichtigen Beitrag zum Profil der Martin-Luther-Universität und ihrer Forschungspartner, des Max-Planck-Instituts für Mikrostrukturphysik und des Fraunhofer-Instituts für Mikrostruktur von Werkstoffen und Systemen. „Das Netzwerk lebt von der Zusammenarbeit der Forschungspartner“, betont Ingrid Mertig den Wert ihres Forschungsschwerpunkts in Halle. In jedem Jahr werden für diesen Forschungsschwerpunkt etwa zehn Millionen Euro Drittmittel eingeworben – die EFRE-Förderung steuert von 2016-2022 zusätzliche Mittel bei und ist damit ein wichtiger Baustein des Forschungsschwerpunkts.
Hinter den 14 Stellen stehen 14 verschiedene Projekte, die von den Post-Docs bearbeitet werden. Diese Projekte sind anwendungsorientiert. Hier gehen jedoch keine Produkte in Serie. Das Ziel der Projekte ist, die Erkenntnisse aus der Grundlagenforschung bis zur Beschreibung einer Anwendung oder zur Anmeldung eines Patents weiterzuentwickeln.
Projektbeispiel: Rekonfigurierbare Dioden
Das Prinzip der rekonfigurierbaren Dioden hat Dr. Ersoy Sasioglu entworfen. Eine Diode ist ein wichtiges Bauelement in der Halbleitertechnologie. „Wir haben bei diesem Projekt basierend auf unserer Materialkenntnis neue Materialien kombiniert, die so in der Natur nicht vorkommen würden. Diese Materialien haben neue Eigenschaften. So entstehen Dioden, die noch kleiner sind, als die, die heute in der Halbleitertechnologie Verwendung finden. „Das Entscheidende ist: Diese Dioden sind rekonfigurierbar. Die Stromrichtung kann nach Bedarf eingestellt werden, die Strom-Spannungskennlinie ist ideal und die Taktfrequenz ist sehr hoch.“ Ein deutsches Patent ist etabliert. Ein Weltpatent ist angemeldet.
09/06/2021: Important contribution to spintronics has received little consideration until now
The movement of electrons can have a significantly greater influence on spintronic effects than previously assumed. This discovery was made by an international team of researchers led by physicists from the Martin Luther University Halle-Wittenberg (MLU). Until now, a calculation of these effects took, above all, the spin of electrons into consideration. The study was published in the journal "Physical Review Research" and offers a new approach in developing spintronic components.
Many technical devices are based on conventional semiconductor electronics. Charge currents are used to store and process information in these components. However, this electric current generates heat and energy is lost. To get around this problem, spintronics uses a fundamental property of electrons known as spin. "This is an intrinsic angular momentum, which can be imagined as a rotational movement of the electron around its own axis," explains Dr Annika Johansson, a physicist at MLU. The spin is linked to a magnetic moment that, in addition to the charge of the electrons, could be used in a new generation of fast and energy-efficient components.
Achieving this requires an efficient conversion between charge and spin currents. This conversion is made possible by the Edelstein effect: by applying an electric field, a charge current is generated in an originally non-magnetic material. In addition, the electron spins align, and the material becomes magnetic. "Previous papers on the Edelstein effect primarily focused on how electron spin contributes to magnetisation, but electrons can also carry an orbital moment that also contributes to magnetisation. If the spin is the intrinsic rotation of the electron, then the orbital moment is the motion around the nucleus of the atom," says Johansson. This is similar to the earth, which rotates both on its own axis and around the sun. Like spin, this orbital moment generates a magnetic moment.
In this latest study, the researchers used simulations to investigate the interface between two oxide materials commonly used in spintronics. "Although both materials are insulators, a metallic electron gas is present at their interface which is known for its efficient charge-to-spin conversion," says Johansson. The team also factored the orbital moment into the calculation of the Edelstein effect and found that its contribution to the Edelstein effect is at least one order of magnitude greater than that of spin. These findings could help to increase the efficiency of spintronic components.
09/04/2021: American Physical Society honors Jürgen Henk
The American Physical Society (APS) has named PD Dr. Jürgen Henk from the Institute of Physics at MLU an "Outstanding Referee". In doing so, the professional association honors the physicist's volunteer work as a reviewer for the society's scientific journals. He has been involved as a reviewer for the journals of the APS and other journals for 25 years.
Before a scientific study is published in a scientific journal, it goes through the peer review process: Independent researchers review the manuscript, provide suggestions for improvement, and ultimately evaluate whether the study should appear in the respective journal. Around the world, many scientists take on these tasks in addition to their actual jobs - unpaid. Jürgen Henk, a solid-state physicist from Halle, is one of them. "On average, I review one manuscript a month for the APS alone," he says. In addition, there are other reviews for other journals.
06/08/2020: Spintronics:
Researchers show how to make non-magnetic materials magnetic
A complex process can modify non-magnetic oxide materials in such a way to make them magnetic. The basis for this new phenomenon is controlled layer-by-layer growth of each material. An international research team with researchers from Martin Luther University Halle-Wittenberg (MLU) reported on their unexpected findings in the journal "Nature Communications".
The theoretical calculations and explanations for this newly discovered phenomenon were made by Ingrid Mertig’s team of physicists. The method was then experimentally tested by several research groups throughout Europe - including a group led by Professor Kathrin Dörr from MLU. They were able to prove the magnetism in the materials. "This combination of computer simulations and experiments enabled us to decipher the complex mechanism responsible for the development of magnetism," explains Mertig.
The study builds upon the work of the former Collaborative Research Centre 762 "Functionality of Oxide Interfaces" at MLU, which was funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) from 2008 to 2019.
04/03/2020: Magnetic whirls in future data storage devices
Magnetic (anti)skyrmions are microscopically small whirls that are found in special classes of magnetic materials. These nano-objects could be used to host digital data by their presence or absence in a sequence along a magnetic stripe. A team of scientists from the Max Planck institutes (MPI) of Microstructure Physics in Halle and for Chemical Physics of Solids in Dresden and the Martin Luther University Halle-Wittenberg (MLU) has now made the observation that skyrmions and antiskyrmions can coexist bringing about the possibility to expand their capabilities in storage devices. The results were published in the scientific journal "Nature Communications".
With the ever-increasing volumes of digital data from the growing numbers of devices, the demand for data storage capacity has been enhanced dramatically over the past few years. Conventional storage technologies are struggling to keep up. At the same time, the ever-increasing energy consumption of these devices - hard disk drives (HDD) and random-access memories (RAM) - is at odds with a "green" energy landscape. Required are entirely new devices that have greater performance at a drastically reduced energy consumption.
A promising proposal is the magnetic racetrack memory-storage device. It consists of nanoscopic magnetic stripes (the racetracks) in which data is encoded in magnetic nano-objects, typically by their presence or absence at specified positions. One possible nano-object is a magnetic (anti)skyrmion: this is an extremely stable whirl of magnetization with a size that can be varied from micrometers to nanometers. These objects can be written and deleted, read and, most importantly, moved by currents, therefore allowing the racetrack to be operated without any moving parts. "By stacking several racetracks, one on top of each other, to create an innately three-dimensional memory-storage device, the storage capacity can be drastically increased compared to solid state drives and even hard disk drives. Moreover, such a racetrack memory device would operate at a fraction of the energy consumption of conventional storage devices. It would be much faster, and would be much more compact and reliable", explains Prof Stuart Parkin, director of the MPI of Microstructure Physics in Halle and Alexander von Humboldt Professor at the MLU.
"Skyrmions and antiskyrmions are 'opposite’ magnetic whirls. However, until recently, it was believed that these two distinct objects can only exist in different classes of materials." explains Prof Ingrid Mertig from the institute of physics at MLU. The research team from Max Planck institutes in Halle and Dresden and the MLU has now discovered that antiskyrmions and skyrmions can coexist under certain conditions in the same material. Dr Börge Göbel, a member of Mertig’s research group, provided the theoretical explanation for the unexpected experimental observations that were carried out by Jagannath Jena in Parkin’s group. The measured single crystal materials, Heusler compounds, were prepared by Dr Vivek Kumar in the group of Prof Claudia Felser at the MPI in Dresden.
08/10/2019: Patented concept from Halle: novel magnetic tunnel diodes and transistors
Today's computer processors are increasingly pushed to their limits due to their physical properties. Novel materials could be the solution. Physicists from Martin Luther University Halle-Wittenberg (MLU) have investigated if and how these materials might be developed. They have proposed a new device concept that utilises the latest findings from the field of spintronics and filed a patent. The team reported on their research in the journal "ACS Applied Electronic Materials".
With their new concept, the researchers at MLU want to unify memory and logic in a single device, which might render possible an all-in-one chip solution for computing. Common processors use billions of transistors to process data. "The energy efficiency of these individual components determines how much energy is consumed by the processor overall," says Professor Ingrid Mertig, a theoretical physicist at MLU. Energy loss, which occurs when electrical energy is converted into heat, remains the biggest challenge, she explains. When developing these components, scientists also have to decide whether to create very powerful and energy-efficient components that can only be used for a specific purpose, or to create parts that can be used in a variety of ways, but which have a lower performance and require more energy. For its latest innovation, the team of researchers investigated whether spintronics can be used to solve these problems.
"Our proposals for the new diodes and transistors combine data processing and storage. There is no loss of energy to store date and they can be reconfigured," explains Dr Ersoy Şaşıoğlu, a physicist at MLU and first author of the paper. A patent has already been filed for the design of these spintronic components.
09/09/2019: Spintronics: Physicists discover new material for highly efficient data processing
A new material could aid in the development of extremely energy efficient IT applications. The material was discovered by an international research team in cooperation with Martin Luther University Halle-Wittenberg (MLU). The electrons at the oxide interface of the material possess special properties which drastically increase the conversion rate of spin current to charge current. This is the foundation for future spintronic applications. The new material has been found to be more efficient than any previously investigated material, the team writes in the journal "Nature Materials".
Electric current flows through all technical devices. Heat is generated and energy is lost. Spintronics explores new approaches to solving this issue that utilise a special property of electrons: spin. This is a type of intrinsic angular momentum of electrons that generates a magnetic torque and it is what causes magnetism. The idea behind spintronics is: If spin current flows through a material instead of an electrical charge, no heat is generated and significantly less energy is lost in the device. "However, this approach still requires an electric current for the device to work. Therefore, an efficient spin-to-charge conversion is necessary for this novel technology to work," explains Professor Ingrid Mertig, a physicist at MLU. Her research group is part of the international research team that discovered the new material. The work was led by the French physicist Dr Manuel Bibes, who conducts research at the renowned institute Centre national de la recherche scientifique (CNRS) - Thales.
The group investigated the interface between two oxides. "The two substances are actually insulators and are non-conductive. However, a kind of two-dimensional electron gas forms at their interface, which behaves like a metal, conducts current and can convert charge current into spin current with extremely high efficiency," explains Mertig. Dr Annika Johansson and Börge Göbel, two members of her research group, provided the theoretical explanation for this unusual observation. According to the researchers, the new material is significantly more efficient than any other known material. This could pave the way for the development of new, energy-saving computers.
27/04/2018: Halle physicists on the road to success
Successful knowledge transfer requires excellent basic research which is run by the researchers of the Institute of Physics at the university, where not only three Collaborative Research Centres (SFB) of the German Research Foundation and an Alexander von Humboldt Professorship are located. The researchers also have excellent international networks and regularly attract attention with publications in renowned scientific journals.
The Institute of Physics at Martin Luther University, which is comparatively small with 14 professorships, is currently funded by three Collaborative Research Centres of the German Research Foundation. In detail, these are the SFB 762 "Functionality of Oxide Interfaces", which was established in 2008, the Transregio-SFB 102 "Polymers under Constraints" established with the University of Leipzig in 2011, and the Transregio-SFB 227 "Ultrafast Spin Dynamics" , newly acquired last year together with Freie Universität Berlin. All three initiatives are embedded in the scientific research network "Materials Science - Nanostructured Materials" at the University, which deals with the development of novel materials and innovative measurement methods.
The Institute of Physics at the Martin Luther Unievrsity has also made a name for itself worldwide - both as a venue for international conferences and as an institution for highly respected guest scientists. Together with the Max Planck Institute of Microstructure Physics , the physicists succeeded in bringing the inventor of modern hard disk technology, Prof. Dr. Stuart Parkin, to Halle in 2013 via an Alexander von Humboldt Professorship - Germany's highest endowed international research prize. The French Physics Nobel Prize winner Prof. Dr. Albert Fert has also been a guest of the institute since 2014. And only a few weeks ago, Dr. Manuel Bibes from the renowned Centre national de la recherche scientifique (CNRS) Thales was awarded the Friedrich Wilhelm Bessel Research Award by the Alexander von Humboldt Foundation to work in Halle for several months.
17/12/2015: Hugo Junkers Award for Nicki Hinsche
Physicist Dr. Nicki Hinsche has been awarded the first prize in the category Basic Sciences of the Hugo Junkers Innovation Award Saxony-Anhalt 2015 for the project "Nanostructured thermoelectric layered systems". "I traveled all the way from Copenhagen for the award", says Dr. Nicki Hinsche, who now works at the Technical University of Denmark. For his project he received the 10,000 euros first prize for the most innovative project in the Basic Sciences category. The researchers, for example, make use of waste heat, which is generated by technical devices but also by living organisms and released into the environment, in order to convert it into electrical energy.
