摘　　要：本文综述了新型稀土永磁材料研究现状，主要包括辐射各向异性稀土混合磁体，耐热SmFeN（各向异性）磁体、d—HDDR新工艺度其“MAGFINE”磁体和柔性磁体等；同时介绍了纳米复合磁体的研发，以厦热变形法制备全致密磁体的工艺进展。The current study on the novel rare - earth permanent magnetic materials were summarized. Rare - earth permanent, such as anisotropic radiation mixture magnets, heat- resistant SmFeN （anisotropic） magnets, d- HDDR process and ＂MAGFINE＂ magnets, and flexible material were discussed. Also the recent development of nano - composite permanent materials and fully - dense magnets prepared by hot - deformation process were presented.
