| 简介 |
A rare-earth magnet material provided with : a first phase including a compound constituted from at least one type of rare-earth element R including Nd, at least one type of transition metal element T including Fe, and at least one type of element X selected from B and C, the compound being represented by RαTβX, where α is the composition ratio of R and β is the composition ratio of T; a grain boundary phase present in a crystal boundary of the first phase and having a higher R concentration than the RαTβ; and a second phase including a compound constituted from at least one type of rare-earth element S including Sm and at least one type of transition metal element M including Co, the compound being represented by SγMδ, where γ is the composition ratio of S, and δ is the composition ratio of M. |
