The Role of Cu in Sintered Nd-Fe-B Magnets: ab initio Study

Trace addition of Cu is an effective method to improve the coercivity of sintered NdFeB magnets via improving the microstructure. The efficiency of Cu doping depends on the distribution of Cu in the multi-phase microstructure of the NdFeB magnet. To understand and control the Cu redistribution, the...
