RARE EARTH MAGNET AND PROCESS FOR PRODUCING SAME

摘要

A process for producing a rare earth magnet comprises: an adhesion step of causing a diffusion element capable of diffusing inwardly to adhere to the surface part of a magnet material comprising a compact or sintered body of rare earth alloy particles; and an evaporation step of heating the magnet material in vacuum to evaporate at least a portion of the diffusion element having been retained on or in the surface part of the magnet material.
