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.

摘要： To provide a molded magnet which simultaneously satisfies increased film thickness, high density, and improved magnetic properties (in particular, coercive force, residual magnetic flux density, and tight adhesion).
The problem can be solved by a molded rare-earth magnet having a rare-earth magnet phase that contains as a main component a nitride which contains Sm and Fe, in which the molded rare-earth magnet has a density of 80% or higher of the theoretical density of a molded magnet constituted of the rare-earth magnet phase, and has a structure in which particles of Zn and/or Mn have been dispersed in the molded magnet.摘要翻译： 提供同时满足增加的膜厚度，高密度和改善的磁性（特别是矫顽力，剩余磁通密度和紧密粘合）的模制磁体。 该问题可以通过具有稀土类磁体相的成型稀土类磁体来解决，所述稀土类磁体相以包含Sm和Fe的氮化物为主要成分，其中，成型稀土类磁体的密度为80％以上 由稀土类磁铁相构成的模制磁体的理论密度，并且具有将Zn和/或Mn的粒子分散在模制磁体中的结构。
