| 简介 | A rare earth permanent magnet alloy with a high coercive force is disclosed. The rare earth permanent magnet alloy comprises : a rare earth-iron-boron type magnetic phase (R 2 Fe 14 B type magnetic phase) constituting a parent phase; and a defect structure. The parent phase contains the defect structure. Displacement of magnetic domain wall of the R 2 Fe 14 B type magnetic phase is prevented by the defect structure, thereby improving coercive force. | ||
