摘要:

我们用两种互补的实验方法研究了铁磁体/拓扑绝缘体界面的激光驱动自旋电流效应。研究了铁磁/拓扑绝缘体双层膜中的直流光电流。动态界面电流探索通过发射太赫兹辐射发射这些电流具有高的时间分辨率。从我们的实验中,我们揭示了铁磁体和拓扑绝缘体界面的横向和动态相互作用。

英文摘要:

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.
