摘要
采用计算机模拟的方法计算了纳米晶复合永磁材料的磁性能 ,并对软磁相比例对磁性能的影响进行了研究。结果显示 ,当软磁相比例增加时 ,由于软磁相高的饱和磁极化强度以及软硬磁相间的交换耦合作用的影响 ,剩磁逐渐增加 ,但矫顽力则随着软磁相的增加而逐渐下降。
Magnetic properties of a model nanocomposite magnet were calculated by means of computer simulation, and the effects of the amount of the soft magnetic phase on them were studied. The numerical results show that the remanence enhances with the increase of the soft grains, it is due to the high spontaneous magnetication of soft magnetic phases and exchange interactions, but the coercivity decreases.
