High-coercivity heavy-rare-earth-free NdFeB sintered magnets developed by doping Ce85Al15 and grain boundary diffusion with Pr70Cu15Al15
Traditional NdFeB sintered magnets with coercivity larger than 20 kOe, called super-high (SH) level, usually contains considerable amount of high-cost heavy rare earth (HRE), such as Dy or Tb. In this work, high coercivity of 21.4 kOe, which corresponds to SH level, is achieved for HRE-free NdFeB ma...
