论文摘要
表面等离子体极化（SPP）是一种电磁波，在金属表面处的衍射极限超出衍射极限。最近，理论上提出了SPP和电子之间的角动量转换。在这项工作中，我们成功地测量了SPP诱导的自旋电流，这证明了角动量互连的事实。从光电流到旋转电流的这种转换可以用作使用光学数据传输或存储的下一代旋转计算中的耦合器。
Surface plasmon polariton (SPP) is an electromagnetic wave which is tightly localised beyond the diffraction limit at metallic surfaces. Recently, it is theoretically proposed that the angular momentum conversion between the SPP and electrons. In this work, we have successfully measured SPP induced spin currents, which proves the fact that the angular momenta are interconverted. Such conversion from light to a spin current can be used as a coupler in a next generation spintronic computing with optical data transfer or storage.
