摘　　要：永磁材料的发展先后经历了金属永磁材料、铁氧体永磁材料、稀土永磁材料、纳米结构永磁材料等几个发展阶段,超导永磁体则是学术界近年来提出的一种新概念永磁体。本文在对永磁材料的发展历史和发展趋势进行了综合分析之后,对永磁材料今后的发展做出了预测。The development of permanent magnetic materials has experienced several stages as metal, ferrite, rare-earth, and nano-structured permanent magnetic materials, and superconducting permanent magnet is a new concept permanent magnet suggested by researches in recent years. Based on the synthetical analysis of the history and developing tendency of permanent magnetic materials, the development of permanent magnetic materials in future was predicted.
