COMBINED TYPE RFeB-BASED MAGNET AND METHOD FOR PRODUCING COMBINED TYPE RFeB-BASED MAGNET |
| 摘要 |
Provided is a combined type RFeB-based magnet, including: two or more unit magnets; and an interface material that bonds bonding surfaces of the unit magnets adjacent to each other, in which each of the unit magnets is an RFeB-based magnet containing a light rare earth element RL that is at least one element selected from the group consisting of Nd and Pr, Fe, and B, in which the interface material contains at least one compound selected from the group consisting of a carbide, a hydroxide, and an oxide of the light rare earth element RL, and in which the combined type RFeB-based magnet contains at least one element selected from the group consisting of Dy, Ho and Tb, and has a nonplanar surface. |

1. A combined type RFeB-based magnet, comprising:
two or more unit magnets; and an interface material that bonds bonding surfaces of the unit magnets adjacent to each other, wherein each of the unit magnets is an RFeB-based magnet containing a light rare earth element RL that is at least one element selected from the group consisting of Nd and Pr, Fe, and B, wherein the interface material contains at least one compound selected from the group consisting of a carbide, a hydroxide, and an oxide of the light rare earth element RL, and wherein the combined type RFeB-based magnet contains at least one element selected from the group consisting of Dy, Ho and Tb, and has a nonplanar surface. |
