微磁学是磁学的一个分支。其研究对象为介观尺度下铁磁体的磁化过程。该尺度足够大，大到到原子的大小可忽略不计，因此在该尺度下材料的磁学特性是连续的；然而该尺度又足够小，小到可以看清磁畴的结构。

In this thesis, the reversal mechanism of the oriented and unoriented two-phase multilayers has been investigated in detail based on Brown’s micromagnetics. The results have been extended to nano composite magnets(bulk materials) with the dominant coercivity mechanism obtained.
