Spin orbit coupling in heavy metals allows conversion of unpolarized light into an open-circuit voltage. We experimentally prove that this photo-spin voltaic effect is due to photo-excitation of carriers in the proximized layer and can exist for light in the visible range. While carrying out the experiment, we discovered that, in closed-circuit conditions, the anisotropic magnetoresistance of the proximized metal is a function of the light intensity. We name this effect photo-magnetoresistance. A magneto-transport model is presented that describes the change of magnetoresistance as a function of the light intensity.

接近铂的光自旋伏打效应和光磁电阻

重金属中的自旋轨道耦合允许将非偏振光转换为开路电压。我们通过实验证明，这种光自旋伏打效应是由于邻近层中载流子的光激发引起的，并且可以存在于可见光范围内。在进行实验时，我们发现，在闭路条件下，邻近金属的各向异性磁阻是光强度的函数。我们将此效应命名为光磁电阻。提出了磁传输模型，该模型描述了作为光强度函数的磁阻变化。
