纳米晶复合交换耦合软磁和硬磁材料的研究进展

Development of Nanocrystalline Composite Exchange-Coupling Soft and Permanent Magnetic Materials

论述了纳米晶复合交换耦合软磁和硬磁材料的概念、结构、性能和特点,着重讨论了二者之间的异同点,并从细化晶粒的角度阐述了二者之间的可相互借鉴性。

The microstructure and properties of nanocrystalline composite exchange coupling soft and permanent magnetic materials are summarized in this paper, with emphasis on the similarity and difference between them. The grain-size effects on the properties are also dis-cussed. The development of nanocrystalline soft magnetic materials highlights the way to im-prove the properties of permanent magnetic materials.
