纳米复合永磁材料中软硬磁性相间交换耦合作用的表征

摘要

软硬磁性相间的交换耦合作用对纳米复合永磁材料的性能有重要的影响。介绍了目前几种常用的表征软硬磁性相间交换耦合作用强弱的方法，并相应地给出了一些典型的测量结果。%Exchange coupling interaction between hard and soft magnetic phases has an important influence on the performance of the nanocomposite permanent materials.Several common methods of characterizing inter-phase exchange coupling interaction are presented,and accordingly some typical measurement results are given in this paper.
