| description | To provide a low-cost rare earth magnet including Ce, which is high in HcJ.SOLUTION: There is provided an R-T-B based permanent magnet including main phase particles comprising an R2T14B compound (R represents a rare earth element, T represents a transition metal element, and B represents boron), and grain boundaries. R includes Ce. The grain boundaries include multi-particle boundaries adjacent to three or more main phase particles. The multi-particle boundaries include an R rich phase, the R rich phase including plate-shaped or needle-shaped R-T precipitates.SELECTED DRAWING: Figure 1B
【課題】Ｃｅを含む低コストな希土類磁石であって、ＨｃＪが高い希土類磁石を得る。【解決手段】 Ｒ２Ｔ１４Ｂ化合物（Ｒは希土類元素、Ｔは遷移金属元素、Ｂはホウ素）からなる主相粒子と、粒界と、を含むＲ－Ｔ－Ｂ系永久磁石である。ＲはＣｅを含む。粒界は、３個以上の主相粒子と隣接する多粒子粒界を含む。多粒子粒界はＲリッチ相を含み、Ｒリッチ相に板状または針状のＲ－Ｔ析出物が含まれる。【選択図】図１Ｂ |
