Magnets: Key materials for green energy

New collaboration between TU Darmstadt and MPIE

2020/10/21 by

The Technical University Darmstadt and the Max-Planck-Institut für Eisenforschung (MPIE) started a new Max Planck Research Group headed by Prof. Oliver Gutfleisch, Professor of Functional Materials at the TU Darmstadt and scientific director at the Fraunhofer IWKS Materials Recycling and Resource Strategies. The group is established at the MPIE and deals with the design of advanced hard and soft magnets, magnetocaloric and related functional materials.

“Magnets are key materials for electrification thus providing sustainable mobility and energy applications. My expertise in designing magnets and the MPIE’s expertise in correlative electron microscopy and tomography down to the atomic scale make an ideal combination to push functional bulk magnets to their physical limits.“, explains Gutfleisch. “I am very happy and proud that we could win Oliver for this group.", states Prof. Dierk Raabe, managing director at the MPIE.

The new group “De Magnete – Designing Magnetism on the Atomic Scale” analyses the critical magnetization reversal processes on the atomic scale using advanced experimental and simulation methods. The aim is to capture, reproduce and predict transitional and dynamic processes that are relevant for nucleation and propagation during all critical magnetization reversal processes on all length scales. Magnets are used in many fields of daily life and industry like in energy conversion, electromobility, data storage and robotics. Their enhancement is key to a carbon neutral economy.

An already existing successful collaboration between Prof. Gutfleisch and the MPIE is the Collaborative Research Centre/Transregio 270 “Hysteresis design of magnetic materials for efficient energy conversion” which is funded by the German Research Foundation. Dr. Baptiste Gault, head of the MPIE group “Atom Probe Tomography”, Prof. Gutfleisch and experts of the University Duisburg-Essen and the Ernst-Ruska Centre for Microscopy and Spectroscopy with Electrons are working on adjusting the local and global properties of magnetic materials by additive manufacturing and severe plastic deformation methods.
