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.
- Science in Berlin: collaborative, diverse, innovative, internationalScience is a key social and economic factor for Berlin. It creates jobs and adds value, attracts talent from all over the world, and enriches city life. To ensure that Berlin remains one of the world’s leading centres of science in the future, science must feature even more prominently on the political agenda. This is what BR50 stands for: over 50 non-university research institutions, including the HZB, are joining forces in this network. Following the election in Berlin, BR50 is now addressing politicians with a position paper, accompanied by the campaign “𝗪𝗶𝗿 𝗳𝗼𝗿𝘀𝗰𝗵𝗲𝗻 𝗳ü𝗿 𝗕𝗲𝗿𝗹𝗶𝗻.”
- Does African Architecture exist?The world’s first Pan-African Architecture Biennale took place this September in Nairobi, Kenya. People from the worlds of architecture, art, academia and politics from 54 African countries and the diaspora had travelled to Nairobi to exchange ideas on traditional and contemporary building methods, materials, experiences and projects. Samira Aden co-organised this biennial as lead curator. We spoke to her about it.
- Nanosilver as an electrocatalyst for CO₂ reductionVia electrolysis, CO2 can be reduced to CO, a raw material for further chemical products such as fuels. Within the GreenQuest Project, an internation team led by HZB chemist Prashanth Menezes has now systematically investigated catalyst layers made of silver nanoparticles, varying both the size of the particles and their density. The best yield was achieved with nanoparticles with diameters of around 10 nm, which were loosely distributed. Furthermore, they demonstrated how the economic efficiency of the electrochemical cell can be enhanced by integrating an additional chemical reaction at the anode, enabling the simultaneous production of a valuable formic acid, hydrogen, and CO in one device.
