DESCRIPTION:Efficient energy converters require high-performance magnetic m
 aterials such as rare earth permanent magnets. Due to the criticality of r
 are earth metals\, the major challenges are the reduction or avoidance of 
 those elements in permanent magnets and to optimize the microstructure to 
 approach theoretical predictions of micromagnetism. For better sustainabil
 ity\, it is furthermore expected for the materials to secure long-lasting 
 use with subsequent recycling options. Possible solutions include: (1) In-
 depth quality assessment of magnets: A good process quality is the prerequ
 isite for a long magnet lifetime. Defects cause premature demagnetization 
 and thus aging of the magnets. Different microscopy techniques in combinat
 ion with quantitative image analysis as well as component testing are deve
 loped as tools for quality assurance. (2) Tailoring and optimization of ma
 terials to the requirements of the electrical machine: Starting from well-
 known microstructure-property relations the magnetic properties can be tai
 lored from a sustainability and economic point of view. Ce-substituted mag
 nets and directly recycled magnets are particularly promising. (3) Identif
 ication of new materials and new technologies: Bulk high-throughput method
 s allow to explore completely new hard magnetic phases. The extent to whic
 h laser powder bed fusion additive manufacturing can lead to good magnetic
  properties and new perspectives needs to be examined. The presentation gi
 ves insight into the different solutions.\nSpeaker: Prof. Dagmar Goll
