论文摘要
我们通过两种互补的实验方法研究激光驱动的旋转效应在铁磁/拓扑界面界面上。 DC光电流在具有高空间分辨率的铁磁性/拓扑结构剂双层中进行了研究。通过具有高时间分辨率的这些电流发射的Terahertz辐射的发射来探索动态界面电流。从我们的实验中,我们揭示了铁磁体和拓扑绝缘子界面的横向和动态相互作用。
We study laser driven spin-current effects at ferromagnet/topological-insulator interfaces by two complementary experimental approaches. The DC photocurrent is studied in ferromagnet/topological-insulator bilayers with high spatial resolution. Dynamic interface currents are explored via the emission of terahertz radiation emitted by these currents with high temporal resolution. From our experiments, we reveal a lateral and dynamic interaction of the ferromagnet and the topological insulator interface.
