Spin transport in noncollinear antiferromagnetic metals
Physical Review B ( IF 3.7 ) Pub Date : 
Yihong Cheng, Shufeng Zhang

For non-collinear antiferromagnetic metals, magnon spectra display non-trivial multi-band structure in which both direction and magnitude of the angular momenta of magnons are momentum-dependent. We study the roles of these magnons on the spin transport properties by taking into account the momentum and angular momentum transfer between conduction electrons and magnons. We have calculated spin conductivity tensor by using the coupled Boltzmann equations for the electron spin and magnon, and we show that the unpolarized electron current driven by an electric field can efficiently induce a magnon spin current. The temperature dependence of the magnon spin conductivity is also calculated.

非共线反铁磁性金属中的自旋输运

对于非共线反铁磁性金属,磁振子频谱显示非平凡的多频带结构,其中磁振子角动量的方向和大小都与动量有关。我们通过考虑传导电子和磁振子之间的动量和角动量转移,研究了这些磁振子对自旋输运性质的作用。我们通过使用耦合的玻尔兹曼方程对电子自旋和磁振子计算了自旋电导张量,并且我们证明了由电场驱动的非极化电子电流可以有效地感应出磁振子自旋电流。还计算了磁振子自旋传导率的温度依赖性。
