我们从微观上推导了非局域自旋阀结构系统中由非平衡自旋积累产生的扩散自旋流引起的自旋转移力矩。通过引入磁性杂质，考虑了自旋输运中的自旋弛豫效应。
We microscopically derive the spin-transfer torque due to diffusive spin current arising from nonequilibrium spin accumulation as realized in systems with nonlocal spin valve structure. Spin relaxation effects in spin transport is taken into account by introducing magnetic impurities.
