earth crisis", there has been a revived interest in sintered NdFeB permanent magnets because of their outstanding comprehensive properties. The microstructure and chemical structure/ composition characteristic of the grain boundary, as well as the intrinsic properties of Nd2Fe14B matrix phase, are closely related to the magnetic properties of sintered NdFeB magnets. Recent nanoscale characterization......
