Rashba-type spin-orbit effects by spin-resolved photoemission — •Oliver Rader — Helmholtz-Zentrum Berlin

In order to create spin currents in a solid, the Rashba effect can be instrumental. It requires neither a ferromagnetic material nor external magnetic fields. In this talk, we show that a quantum cavity for spin can be constructed from metals. Spin- and angle-resolved photoemission is used to study the dependence of the spin-orbit splitting of quantum-well states on parameters such as momentum and atomic number. In this context, we will also discuss the perspectives of graphene for spintronics.
