Felix Büttner has led a junior research group at HZB. Now he has accepted a call to the University of Augsburg. As head of a joint research group, he will continue his studies of magnetic skyrmions at BESSY II.
Felix Büttner has been leading a junior research group at HZB since the beginning of 2020, funded by the Young Investigator Grant of the Helmholtz Association. In spring 2022, he was awarded the Walter Schottky Prize of the German Physical Society for his pioneering achievements in the field of magnetic skyrmions. Since July, he holds a professorship at the Institute of Physics, University Augsburg.
Felix Büttner studied in Göttingen and received his doctorate in 2013 for his work at the interface of magnetism and X-ray physics. After a stint in industry at Daimler AG, he worked as a postdoctoral researcher at the Massachusetts Institute of Technology from 2015-2020.
Prof. Dr. Büttner investigates nanotextures in magnetic thin-film materials and drives the development of ultrahigh-resolution X-ray microscopy techniques. The aim is to understand the particle-like dynamics of such topological textures and to prepare their application in information technology.
Under a cooperation agreement between the University of Augsburg and HZB, Büttner will work one day a week at HZB, where he runs laboratories in Wannsee and carries out measurements at BESSY II. His research group will remain in full size.
- HZB patent for semiconductor characterisation goes into serial productionAn HZB team has developed together with Freiberg Instruments an innovative monochromator that is now being produced and marketed. The device makes it possible to quickly and continuously measure the optoelectronic properties of semiconductor materials with high precision over a broad spectral range from the near infrared to the deep ultraviolet. Stray light is efficiently suppressed. This innovation is of interest for the development of new materials and can also be used to better control industrial processes.
- Alternating currents for alternative computing with magnetsA new study conducted at the University of Vienna, the Max Planck Institute for Intelligent Systems in Stuttgart, and the Helmholtz Centers in Berlin and Dresden takes an important step in the challenge to miniaturize computing devices and to make them more energy-efficient. The work published in the renowned scientific journal Science Advances opens up new possibilities for creating reprogrammable magnonic circuits by exciting spin waves by alternating currents and redirecting these waves on demand. The experiments were carried out at the Maxymus beamline at BESSY II.
- BESSY II: Heterostructures for SpintronicsSpintronic devices work with spin textures caused by quantum-physical interactions. A Spanish-German collaboration has now studied graphene-cobalt-iridium heterostructures at BESSY II. The results show how two desired quantum-physical effects reinforce each other in these heterostructures. This could lead to new spintronic devices based on these materials.
