 Rashba–Edelstein effect

The Rashba–Edelstein effect refers to a phenomenon observed in spintronic materials, where an electric current can induce a non-equilibrium spin polarization in a system. This effect arises from the interplay between spin-orbit coupling and the flow of charge carriers, typically in two-dimensional electron systems. The Rashba effect, named after physicist Emmanuel Rashba, describes the splitting of electronic states in a system with structural inversion asymmetry due to spin-orbit coupling.
