Patent ID: 10886044

Abstract:
A rare earth permanent magnet that is high in residual magnetization and coercivity is obtained and includes R and T. A main phase of crystal grains having an Nd5Fe17 type crystal structure is included. In an X-ray diffraction profile drawn by performing an XRD measurement for a rare earth permanent magnet, peaks of detected intensity are present in specific ranges. In which the detected intensity of the peak with the highest detected intensity in the range of 41.60°<2θ(°)<42.80° is set as α, the detected intensity of the peak with the highest detected intensity in the range of 34.38°<2θ(°)<34.64° is set as β, and the detected intensity of the peak with the highest detected intensity in the range of 38.70°<2θ(°)<41.20° is set as γ, 0.38<α/β<0.70 and 0.45<γ/β<0.70 are established. The peak with the highest detected intensity in the range of 34.38°<2θ(°)<34.64° is a peak derived from the Nd5Fe17 type crystal structure.
