| 简介 |
The present invention provides a magnet structure comprising a first magnet, a second magnet, and an intermediate layer joining the first magnet and the second magnet. In the magnet structure, each of the first magnet and the second magnet is a permanent magnet comprising a rare earth element R, a transition metal element T, and boron B. In addition, the rare earth element R comprises : a light rare earth element RL comprising at least Nd; and a heavy rare earth element RH, and the transition metal element T comprises Fe, Co, and Cu. Further, the intermediate layer comprises : an RL oxide phase comprising an oxide of the light rare earth element RL; and an RL—Co—Cu phase comprising the light rare element RL, Co, and Cu. |
