报道了周期性畴结构的磁光衍射。周期性畴结构通过将扁平铁磁金属磁性地耦合到磁性元件阵列而在扁平铁磁金属中产生。交换和静磁耦合都是有效的，产生磁化的调制，尽管静磁耦合的效果稍微大一些，因为它有利于相邻畴的反平行排列。微磁学模拟同意定性与实验结果。
Magneto-optic diffraction by a periodic domain structure is reported. The periodic domain structure is generated in a flat ferromagnetic metal by coupling it magnetically to an array of magnetic elements. Both exchange and magnetostatic couplings are effective, creating a modulation of the magnetization, although the effect is somewhat larger for magnetostatic coupling, since it favours an antiparallel alignment of adjacent domains. Micromagnetic simulations agree qualitatively with the experimental findings.
