摘　　要：永磁材料是实现机械能和电能转换的关键材料,在电动汽车、电子产品、风力发电机等领域是必不可少的。不过,高性能稀土永磁铁也有许多局限性,包括关键的材料问题和高温磁性能的退化。为了解决这些问题,业界正在开发新型磁铁,使用更少的稀土材料或以金属合金为基础的无稀土磁铁。本文介绍了新一代永磁材料的研究现状、发展趋势和未来的研究方向,以加速其研究和实现快速产业化。Permanent magnetic materials are essential for converting mechanical and electric energy,and are needed in electric vehicles,electronics,wind turbines,and etc.However,high performance rare-earth element based magnets have many limitations,including critical materials problems and the degradation of magnetic properties at elevated temperatures.There has been increasing international demand to solve these problems,and to develop new magnets with reduced rare earth materials,or free magnets based on metallic alloys.This paper describes current research trends,and state of art and future research directions for next generation permanent magnetic materials,to accelerate their research and rapid industrialization.
