代替タイトル: High Performance Permanent Magnets; How to solve element 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 first present our fundamental research on why the coercivity of permanent magnets with different microstructural features are far below their theoretical limits (magnetic anisotropy field). Furthermore, we will discuss the potential of SmFe12 based compounds and the current challenges to realize these materials as new permanent magnets.
