My research interests encompass a wide variety of magnetism related topics with a main focus on spin transport and magnetization dynamics
Prof. Axel Hoffmann joined the University of Illinois at Urbana-Champaign in summer 2019. Before his appointment at UIUC he was the Senior Group Leader of the Magnetic Thin Film Group within the Materials Science Division at the Argonne National Laboratory. His research interests encompass a wide variety of magnetism related subjects, including basic properties of magnetic heterostructures, spin-transport in novel geometries, and biomedical applications of magnetism. His main research focus has recently been on pure spin currents investigated by magnetotransport and magnetization dynamic measurements. He has more than 200 publications with combined more than 20000 citations (h-index: 68 based on Google Scholar), four book chapters, and three magnetism-related U.S. patents. In addition, he is an Associate Editor for the Journal of Applied Physics. He is a fellow of the American Physical Society, American Vacuum Society, and IEEE. Furthermore, he was in 2011 a Distinguished Lecturer for the IEEE Magnetics Society, received in 2015 the Outstanding Researcher Award by the Prairie Section of the American Vacuum Society, in 2016 was awarded a President’s International Fellowship from the Chinese Academy of Sciences, received in 2017 the Distinguished Performance Award from the University of Chicago, and was selected as a Highly Cited Researcher by the Web of Science each year during in 2019–2022. In 2022 he was awarded the David Adler Lectureship Award in Materials Physics from the American Physical Society.
