Discovery of rare-earth lean high-performance permanent magnets

The development and deployment of high-performance permanent magnets depend on the utilization of suitable magnetic and bonding elements in the anisotropic crystal structure. The first prerequisite is to pinpoint which atoms in the crystal provide magnetization, ferromagnetic transition temperature, and magnetic anisotropy. If these intrinsic permanent magnet properties along with the evolution of microstructure are translated to coercivity and remanence, one can then be equipped with the high-performance permanent magnet. We present here our newly discovered crystallographic site substituted high-performance hexaferrites to rare-earth cobalt to neo magnets applicable in vehicle, wind turbine, magnetic cooling, and other household technologies.
