最近，人们发现Fe/Ni双层膜中的条形磁区具有Neel型磁区，具有一定的手性。通过理论模型计算和计算模拟，我们研究了Dzyaloshinskii-Moriya(DM)相互作用如何在自旋重定向相变时改变由长程偶极相互作用产生的磁条磁畴的性质。DM相互作用会影响磁畴的手性和条形磁畴的大小，并且这种影响依赖于DM矢量的方向。我们分析了修饰量，得到了DML强度与偶极相互作用强度之比的公式。研究了DML对温度引起的自旋重取向转变的影响。(C)2013 Elsevier B.V.保留所有权利，
Recently, the domain walls of stripe domain in Fe/Ni bilayer system are found to have Neel-type domain wall with a definite chirality. We investigated how Dzyaloshinskii-Moriya (DM) interaction modifies the properties of magnetic stripe domains generated by long-range dipole interaction at spin reorientation transitions using a theoretical model calculation and a computational simulation. The chirality of the domain wall magnetism and the size of stripe domains are affected by DM interaction, and the modification depends on the direction of the DM vector. We analyzed the amount of modification and obtained a formulation with the ratio between the strengths of the DMl and dipolar interaction. It is studied how DMl affects the temperature induced spin reorientation transition. (C) 2013 Elsevier B.V. All rights reserved,
