Competition between spin-orbit interaction and Zeeman coupling in Rashba two-dimensional electron gases
Competition between spin-orbit interaction and Zeeman coupling in Rashba two-dimensional electron gases
We investigate systematically how the interplay between Rashba spin-orbit interaction and Zeeman coupling affects the electron transport and the spin dynamics in InGaAs-based 2D electron gases. From the quantitative analysis of the magnetoconductance, measured in the presence of an in-plane magnetic field, we conclude that this interplay results in a …
