纳米复合磁性材料的研究现状

General Review of Present Magnetic Nanocomposites Research

全面系统地介绍了纳米复合材料的研究现状和存在的问题。阐述了其交换耦合及矫顽力 机制。探讨了晶粒界面边界相对交换耦合纳米复合材料性能可能的影响。最后提出了一些值得注 意的研究方向。

The development of research in the magnetic nanocomposites is reviewed in general and systematically. The mechanism of cxchange coupling between the neighbouring grains crossing the boundary and coercivity of different microstructure are discussed. It is also suggested that the boundary phases existed between hard and soft magnetic phases may have an important influence upon the property of the magnets. The problems and some suggestions for further studies are also mentioned.
