PROBLEM TO BE SOLVED: To provide an R-T-B series sintered magnet excellent in magnetization while maintaining a high coercive force H.SOLUTION: An R-T-B series sintered magnet 10 includes: main phase grains 1, composed of RTB type crystals; and grain boundary phases 3, existing around the main grains composed of RTB type crystals. Inside the main phase grains 1, composed of RTB type crystals, soft magnetic phases 4 are generated.SELECTED DRAWING: Figure 1 |
