论文摘要
引入了机械等效系统，以模仿具有扩散自旋传输的多层结构的行为。该类比使人们可以使用现有的机械直觉来预测各种参数对旋转扭矩和自旋依赖性磁倍率的影响。特别是，它提供了对不对称f/n/f旋转阀中自旋扭矩的标志改变行为的理解。它进一步有助于揭示具有超薄N层的设备中自旋磁倍率的奇异行为背后的物理原因。
A mechanical equivalent system is introduced to mimic the behavior of multilayer structures with diffusive spin transport. The analogy allows one to use existing mechanical intuition to predict the influence of various parameters on spin torques and spin-dependent magnetoresistance. In particular, it provides an understanding of the sign-changing behavior of spin torque in asymmetric F/N/F spin valves. It further helps to uncover the physical reason behind the singular behavior of spin magnetoresistance in devices with ultra-thin N-layers.
