PROBLEM TO BE SOLVED: To obtain an anisotropic rare-earth permanent magnet, having a texture such that hard magnetic phases and soft magnetic phases are finely scattered and the axes of easy magnetization of the hard magnetic phases are oriented. SOLUTION: In a method for manufacturing an anisotropic rare-earth permanent magnet, having an internal texture such that hard magnetic phases and soft magnetic phases are finely scattered, an alloy material which is obtained from a quenched thin belt having a composition that can yield hard magnetic phases, soft magnetic phases, and nonmagnetic phases having a melting point lower than that of the magnetic phases have when heat-treated is heat-treated to a temperature higher than the melting point of the nonmagnetic phases or the temperature, at which eutectic crystals occur between the nonmagnetic phases and the other phases, in a state where the belt is pressurized in one axial direction. |
