Circular photogalvanic effects in topological insulator/ferromagnet hybrid structures
T. Schumann, T. Kleinke, L. Braun +12
We study laser driven spin-current effects at ferromagnet/topological-insulator interfaces by two complementary experimental approaches. The DC photocurrent is studied in ferromagn…

Observation of spin Nernst photocurrents in topological insulators
T. Schumann, N. Meyer, G. Mussler +7
The theoretical prediction of topological insulators in 2007 triggered tremendous interest. They are of fundamental interest because of their topological twist in k-space, which co…
