论文摘要
使用对称分析和密度函数理论计算，我们发现了dzyaloshinskii-moriya相互作用的性质，fe $ _3 $ gete $ _2 $单层。我们表明，尽管这种相互作用可能会导致短范围内的磁纹理较小，但在longrange dzyaloshinskii-moriya相互作用沿晶体结构的等效方向上的平面内旋转螺旋体偏爱。尽管我们的结果表明，观察到的NéelSkyrmions无法通过单层级别的dzyaloshinskii-Moriya互动来解释，但他们建议将倾斜的磁纹理出现在fe $ _3 $ _3 $ _2 $ _2 $ _2 $ _2 $ _2 $ nanoflakes或Nanoribbons或Nanoribbons和nanoribbons等人的边界上，并且最有趣的是，该型号可能是同性恋磁性的字体。
Using symmetry analysis and density functional theory calculations, we uncover the nature of Dzyaloshinskii-Moriya interaction in Fe$_3$GeTe$_2$ monolayer. We show that while such an interaction might result in small distortion of the magnetic texture on the short range, on the longrange Dzyaloshinskii-Moriya interaction favors in-plane Néel spin-spirals along equivalent directions of the crystal structure. Whereas our results show that the observed Néel skyrmions cannot be explained by the Dzyaloshinskii-Moriya interaction at the monolayer level, they suggest that canted magnetic texture shall arise at the boundary of Fe$_3$GeTe$_2$ nanoflakes or nanoribbons and, most interestingly, that homochiral planar magnetic textures could be stabilized.
