On this hybrid seminar (physical and on zoom) professor Olle Eriksson and Dr. Leonid Pourovskii will talk about modeling of the structure and properties of rare-earth elements. This seminar is the first in a seminar series more focused on specific questions and problems.
Time:
Tue 2023-10-10 14.00 - 16.00
Location: MSE KTH, Kuben, Binellvägen 23, Stockholm / Zoom
Professor Olle Eriksson: A short introduction to the electronic structure and magnetism of rare-earths.
Rare earths (RE) are the key elements to the modern energy production (magnets) and energy saving (magnetic refrigeration, LEDs) technologies. Eriksson and his colleagues carried out extensive modeling of the electronic structure and magnetism of RE metals.
Dr. Leonid Pourovskii: Crystal-field effects and temperature dependence of magnetic anisotropy in rare-earth-based hard magnets
Recently, Pourovskii made a major methodological achievement that enabled researchers to compute the magnetic anisotropy of RE compounds which determines the high performance RE-based magnets.
The event is co-financed by KTH Materials Platform.

Olle Eriksson
Olle Eriksson is professor the Division of Materials Theory, which is hosted in the Ångström laboratory. The division currently hosts some 80 researchers, counting Professors, Associate Professors, Assistant Professors, Postdocs and PhD students, that are all devoted to the theoretical description of materials. Among the senior staff at this division one may notice Dr.Nordström, Dr. Sanyal, Prof.Ahuja, Prof.Opeeneer, Prof. Black-Schaffer, Prof. Fransson and Prof. Sjöqvist. The activities of the division involve development and applications of methods for describing properties of materials in general, including e.g. electronic structure, magnetism, ion-transport, electron transport, many body physics, and quantum entanglement.
Leonid Pourovskii.
Prof. Eriksson has been active in this field for the past 35 years and has led many EU networks, ERC projects, KAW projects and holds a VR rådsprofessor program. He is since 2022 vice-director for the WISE program (https://wise-materials.org/) that is focused on materials science and sustainable technologies, an effort that is funded by the Knut and Allice Wallenberg foundation.
Leonid Pourovskii
Leonid Pourovskii graduated from the Moscow Institute of Steel and Alloys in 1998 and obtained his PhD from Uppsala University in 2003. Currently, he is a permanent researcher at the Center for Theoretical Physics (CPHT) at Ecole Polytechnique in Palaiseau, France. His research domain is the electronic structure and magnetism of strongly correlated materials. In particular, he has been intensively working on developing ab initio approaches for realistic correlated materials based on the dynamical mean-field theory. His current research is focused on exotic "hidden"-order phases and magnetic excitations in spin-orbit Mott insulators, crystal-field effects and magnetism of magnetic rare-earth-based intermetallics, as well as many-electron effects in iron-based alloys.
