MOLDED RARE-EARTH MAGNET AND PROCESS FOR PRODUCING SAME

摘要

Disclosed is a molded rare-earth magnet (1) which comprises rare-earth magnet particles (2) and an insulating phase (3) present among the rare-earth magnet particles (2). The rare-earth magnet particles (2) have, dispersed therein, segregation regions (4) in which at least one element selected from a group consisting of Dy, Tb, Pr, and Ho has segregated. As a result, the molded magnet can retain high magnetic properties (coercive force) and have excellent heat resistance required for use in motors, etc.
