稀土永磁材料的最近进展

The Current Developmmnt Status of Rare-earth Penmnent Magnetic Materials

围绕近年来稀土永磁材料的研发成果，简要介绍了高性能烧结Nd—Fe—B永磁体，Sm（Co，Cu，Fe，Zr）z高温永磁体，各向异性双相纳米晶复合永磁体及新型各向同性（Sm，Zr）（Fe，Co）zB0.1Nx（Z=9～10）粘结永磁体几种材料的发展近况。

This paper briefly introduces the development status of rare-earth permanent magnet materials including high-performance sintered Nd - Fe- B permanent magnet, Sm （Co, Cu, Fe, Zr）z high temperature permanent magnet, anisotropic double phases nano-crystalline composite permanent magnet, and the new isotropic（Sm, Zr） （Fe, Co） z B0.5 Nx（Z = 9- 10） bonded permanent magnet.
