摘要
介绍了稀土类永磁材料R-Co系、R-Fe-B系和R-Fe-N系3个发展阶段的研究及应用现状,并讨论了通过交换耦合机制改善稀土永磁材料性能的最新研究动向。
The current status of research and application for three stages in rare earth permanent magnetic materials in recent years are described, including R-Co system magnet, R-Fe-B system magnet and R-Fe-N system magnet. Recent work aimed at improving properties of rare earth permanent magnets such as Nd_2Fe_(14)B/α-Fe and SmCo_5/NiO nanocomposite magnetsby exchange coupling is also discussed.
