## Description

- description: '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. '
