摘要
首先回顾了金属永磁材料的近代发展历史,然后从磁学及固体理论的角度,根据晶体结构和优异磁性产生机制的不同,简要综述了Fe-Cr-Co系永磁、稀土永磁材料、PtCo系、双相纳米永磁和新型R-T-M金属间化合物等方面的研究现状。重点介绍了钢铁研究总院近期在高性能金属永磁材料探索方面的进展以及双相纳米永磁材料方面的研究工作。最后展望了新型高性能金属永磁材料的研究和应用前景。
The history of the development of metallic system permanent magnetic materials is reviewed. From the directions of magnetism and solid state theory, and based on the differences of crystal structure and the generant mechanism of excellent magnetic properties, the research status of Fe-Cr-Co, rare-earth permanent magnetic materials, PtCo system, nano-composite permanent magnetic materials, and novel R-T-M intermetallics is reviewed. Recent developments of the Institute in high performance metallic permanent magnetic materials and the nano-composite permanent magnetic materials are mainly introduced. At last, the research and application prospects of new high performance metallic permanent magnetic materials are given.
