具有多片层叠结构的稀土永磁复合磁体及其制备方法
摘要：
本公开涉及具有多片层叠结构的稀土永磁复合磁体及其制备方法。该复合磁体包括层叠的第一片状体和第二片状体；所述第一片状体中含有一种或多种稀土永磁化合物晶体和/或一种或多种软磁相；所述第二片状体中含有一种或多种稀土永磁化合物晶体和/或一种或多种软磁相；所述第二片状体与所述第一片状体具有不同的组成。该复合磁体具有较高的软磁含量和较高的最大磁能积。
摘要（英）：

The present disclosure relates to a rare earth permanent magnet composite magnet having a multi-plate laminated structure and a method of manufacturing the same. The composite magnet includes a firstsheet-like body and a second sheet-like body which are laminated; the first sheet body contains one or more than one rare earth permanent magnetic compound crystals and/or one or more than one soft magnetic phases; the second sheet-like body contains one or more than one rare earth permanent magnetic compound crystals and/or one or more than one soft magnetic phases; the second sheet-like body hasa different composition from the first sheet-like body. The composite magnet has a high soft magnetic content and a high maximum energy product.
