简介 PROBLEM TO BE SOLVED : To provide a rare earth magnet material by which a rare earth magnet high in magnetic powder density and superior in magnetic property can be obtained. SOLUTION : A rare earth magnet material comprises : monocrystalline anisotropic particles including samarium, iron, cobalt and nitrogen and having uniaxial crystal magnetic anisotropy; and polycrystalline isotropic particles including samarium, iron and nitrogen, having isotropy, and binding the anisotropic particles to one another. The content of the anisotropic particles to a total mass of the rare earth magnet material is 50 mass% or more. SELECTED DRAWING : Figure 1 COPYRIGHT : (C)2018, JPO&INPIT
