Noncollinear Spin Current for Switching of Chiral Magnetic Textures
Noncollinear Spin Current for Switching of Chiral Magnetic Textures
We propose a concept of noncollinear spin current, whose spin polarization varies in space even innonmagnetic crystals. While it is commonly assumed that the spin polarization of the spin Hall current isuniform, asymmetric local crystal potential generally allows the spin polarization to be noncolli...

We propose a concept of noncollinear spin current, whose spin polarization varies in space even innonmagnetic crystals. While it is commonly assumed that the spin polarization of the spin Hall current isuniform, asymmetric local crystal potential generally allows the spin polarization to be noncollinear inspace. Based on microscopic considerations, we demonstrate that such noncollinear spin Hall currents canbe observed, for example, in layered Kagome Mn3X (X ¼ Ge, Sn) compounds. Moreover, by referring toatomistic spin dynamics simulations we show that noncollinear spin currents can be used to switch thechiral spin texture of Mn3X in a deterministic way even in the absence of an external magnetic field. Ourtheoretical prediction can be readily tested in experiments, which will open a novel route toward electriccontrol of complex spin structures in noncollinear antiferromagnets. |
