The Collaborative Research Centre/Transregio (CRC/TRR) 270 involves researchers from TU Darmstadt, Universität Duisburg-Essen, Max Planck Institut für Eisenforschung and Ernst Ruska-Centre for Microscopy and Spectroscopy with Electrons (ER-C) at Forschungszentrum Jülich. Their common goal is the development of new magnetic materials for efficient energy technologies. This requires to gain a detailed understanding of the structural, magnetic and electronic interactions within the material in order to adjust the local and global properties by new processing techniques to be developed like additive manufacturing and severe plastic deformation methods. Strong permanent magnets based on rare earth elements are a requirement for future mobility and sustainable electricity generation. The magnetocaloric effect causes a change of temperature of a material by the application of an external magnetic field. This principle will enable us to operate refrigerators and air-conditioning devices quietly, with low energy consumption and without the use of traditional refrigerants, themselves strong greenhouse gases. Within this CRC, they will develop new processing methods for innovative magnet materials. Material scientists, physicists, chemists and process engineers will work on magnetic materials by manipulating individual atoms but also by deforming massive samples. By linking the experimental and theoretical groups together in one centre they will be able to continuously cross-link their developments. Artificial intelligence, which accelerates materials discovery and the rapid identification of the most promising material combinations, will also be employed in HoMMage.
