结合相对论第一性原理计算与微磁模型，我们建立的Dzyaloshinskiii-Moriya相互作用作为一个重要的机制，在薄膜磁性，确定相对于晶格的磁畴的方向，畴壁的类型，和磁化在壁的旋转方向。应用分析两个单层铁在W（110），我们提供了一个解释令人费解的实验数据得到的自旋极化扫描隧道显微镜。
Combining relativistic first-principles calculations with a micromagnetic model, we establish the Dzyaloshinskii-Moriya interaction as an important mechanism in thin-film magnetism, determining the orientation of magnetic domains relative to the lattice, the type of domain wall, and the rotational direction of the magnetization in the wall. Applying the analysis to two monolayers Fe on W(110), we provide an explanation for puzzling experimental data obtained by spin-polarized scanning tunneling microscopy.
