Abstract
The nucleation fields of sintermagnets are determined on the basis of micromagnetism taking into account the deteriorating effects of local stray fields, misaligned grains and reduced anisotropy constants of grain surfaces. It is shown that the nucleation hardening model gives a coherent description of the outstanding properties of RE-Fe-Nd magnets.
