In order to reduce material criticality, can we maybe replace critical raw materials? This is sometimes possible, and there are different approaches to do so. How does substitution influence material need and environmental impacts? Our guest Oliver Gutfleisch, Professor for Functional Materials at TU Darmstadt, Germany, will elaborate on this.

Oliver Gutfleisch has published more than 450 papers in refereed journals, and has given more than 240 invited talks. In 2011 he was an IEEE Magnetics Society Distinguished Lecturer on the topic of Magnet Materials for Energy. He coordinated the State of Hesse LOEWE Excellence Program Response from 2014-2017. He held visiting fellowships and Professorships at CNRS Grenoble, NIMS Tsukuba, Imperial College London, Chinese Academy of Science NIMTE Institute in Ningbo and University of Parma. In April 2017 he was awarded an EU ERC Advanced Grant (Cool Innov) and in September 2018 he received the Prize of the German Materials Society (DGM Prize 2018). He is the speaker of the DFG Cooperate Research Center 270 Hommage – Hysteresis Design of Magnetic Materials for Efficient Energy Conversion. He was elevated to IEEE Fellow in 2020 and is running the external Max-Planck Research Group De Magnete at MPI for Iron Research Düsseldorf since October 2020. In 2021 he received the Rare Earth Permanent Magnet REPM achievement award.
