论文摘要
各向异性交换耦合，例如Dzyaloshinskii-Moriya相互作用（DMI），在旋转纹理的形成和动力学中起着至关重要的作用。这项工作预测了具有重磁杂质的金属中各向异性传导电子自旋密度。 $ dzyaloshinskii $ - $ moriya $ $ $ $ $ $ $ $密度$（dm-sd）的两极分化不是与局部磁矩的共线，而是由重原子的自旋依赖性偏斜散射旋转。 DM-SD诱导金属中的磁矩之间的DMI，因此，它是Rutherman-Kittel-Kasuya-Yoshida旋转密度的各向异性延伸。我们的模型由两个局部磁矩组成，一个局部磁矩，一个带有大型自旋轨道耦合（灯笼或稀土），在游离电子气体中。灯笼旋转控制DM-SD强度和极化，有望成为各向异性耦合的柔性控制机制。
Anisotropic exchange couplings, such as the Dzyaloshinskii-Moriya interaction (DMI), have played a vital role in the formation and dynamics of spin textures. This work predicts an anisotropic conduction electron spin density in metals with heavy magnetic impurities. The polarization of this $Dzyaloshinskii$-$Moriya$ $spin$ $density$ (DM-SD) is not collinear to the localized magnetic moments but rotated by the spin-dependent skew scattering of heavy atoms. The DM-SD induces the DMI between magnetic moments in metals and, therefore, it is the anisotropic extension of the Rutherman-Kittel-Kasuya-Yoshida spin density. Our model consists of two localized magnetic moments, one with a large spin-orbit coupling (a lanthanide or rare earth), in a free electron gas. The lanthanide spin controls the DM-SD strength and polarization, promising a flexible control mechanism for anisotropic couplings.
