Abstract
Spin-resolved photoemission (SRPES) experiments have attracted much attention to investigate not only the spin dependent electronic structures of magnetic thin films and surfaces, but also those of non-magnetic materials, e.g. Rashba spin-split surface electronic states and edge states of topological insulators, etc. To show the utilities of SRPES, we show spin-resolved photoemission spectra of Fe thin films grown on Rh(001) surface and Rashba spin-split surface electronic states of √ 3 × √ 3 BiAg/Si(111). We also present our newly developed SRPES spectrometer equipped with VLEED-type spin detector, which achieves 100 times larger efficiency than those of conventional ones.
