Permanent magnets and methods for their production |
摘要 |
<p>Permanent magnet are described in which the ferromagnetic phase is matched with the grain boundary phase, as well as permanent magnets in which magnetocrystalline anisotropy in the vicinity of the outermost shell of the major phase is equivalent in intensity to that in the inside to suppress nucleation of the inverse magnetic domain. Guidelines for designing permanent magnets having high magnetic performance are provided.</p> |
