摘要:
A rare earth magnet molding (1) of the present invention includes rare earth magnet particles (2), and an insulating phase (3) present among the rare earth magnet particles. Segregation regions (4) in which at least one element selected from the group consisting of Dy, Tb, Pr and Ho is segregated are distributed in the rare earth magnet particles (2). Accordingly, the rare earth magnet molding that has excellent resistance to heat in motor environments or the like while maintaining high magnetic characteristics (coercive force) is provided.
