摘　　要：利用密度矩阵方法,我们研究了单势垒量子阱中自旋抽运电流,发现当量子阱中的电子发生自旋电子共振时,自旋抽运电流出现极大值。By using density matrix, we studied the spin-pump current in single quantum well and found that spin-pump current comes to its peak when the electrical spin resonancε of electrons happens in single potential barrier and quantum well.

关 键 词：自旋共振 自旋电流 抽运电流
