Research Abstract

(1) We have developed an ultra-high-vacuum surface-magneto-optical Kerr effect (UHV-SMOKE) system to investigate magnetic properties of surface states. The method has revealed that the magnetic property of Cobalt atomic layers sensitively depends on the substrate structures beneath them. (2) We have revealed, by using spin-resolved photoemission spectroscopy and the first-principle calculations, that the surface states of non-magnetic materials, Bismuth and its alloys (topological insulators), are spin-split. (3) We have directly detected (inverse) spin-Hall effect on Bismuth film surfaces that have large spin-orbit interaction, by measuring surface-state transport with a four-tip STM (scanning tunneling microscope) apparatus.
