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.
- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- An important step towards detecting fractons in quantum spin liquidsFollowing predictions of the existence of fractons in quantum spin liquids by more general gauge field theories, researchers at HZB succeeded in detecting these quasi-particles also in a quantum solid-state model.
- Hatice Mutlu appointed to the Helmholtz Institute HIPOLE in JenaProf. Dr Hatice Mutlu is the new professor of sustainable polymer chemistry at HIPOLE Jena, the Helmholtz Institute for Polymers in Energy Applications. On 17 August 2026, she visited the HZB campus in Berlin-Adlershof including the BESSY II lightsource and discussed future collaboration with researchers and the board of directors.
