摘要: Permanent magnets in which the ferromagnetic phase is matched with grain boundary phase, and permanent magnetocrystalline anisotropy vicinity of outermost shell major equivalent intensity to that inside suppress nucleation reverse magnetic domain, more specifically having a not less than one-half interiors grains, are disclosed.
