## 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 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.
