Abstract
A large number of sintered Nd-Fe-B based magnets with three different heat treatments and also substituted samples (Nd by Dy, Fe by Co or both) were investigated by measuring the temperature dependence of both coercivity and anisotropy field. Additionally the ratio between Nd and (Fe, B) was varied systematically. These data were analysed using a nucleation model description. The reliability of this model was proved by comparing the analysis with that performed on a Sm2Co17 based magnet.
