Rare earth permanent magnet |
| abstract |
To provide a rare earth permanent magnet having a high coercive force using Pr having a large magnetic anisotropy. The abundance ratio P4 / (P3 + P4) is P4 / (P3 + P4) ≧ 0.1 when the number of trivalent Pr atoms in the main phase particle is P3 and the number of tetravalent Pr atoms is P4. It is characterized by that. Thereby, the effect | action of the improvement of the magnetic anisotropy derived from tetravalent Pr is acquired, and the rare earth permanent magnet with a high coercive force can be obtained. [Selection figure] None |
