代替タイトル: Design and development of permanent magnets; how to solve rare-earth criticality while considering new demands?

説明:

Permanent magnets are widely used in green energy conversion and play an important role in achieving net-zero CO2 emissions. In order to maintain sustainable production of permanent magnets in the long term, it is necessary to eliminate the dependence of permanent magnets on critical elements such as Dy and to diversify the use of rare earths while maintaining their performance close to their theoretical limits. In this talk, we will present recent advancement of development of Dy-free Nd-Fe-B permanent magnets with their ultimate performance. Moreover, we will present potential of SmFe12-based permanent magnets as the next generation rare-earth lean high performance permanent magnets.
