Paper Abstract

For a two-dimensional electron gas, the breaking of inversion symmetry induces a Rashba spin-orbit coupling which modifies its band electronic structure. A clear manifestation of this effect can be observed in the behavior of the electrical resistance in magnetic field. In this paper we study a two-dimensional electron gas at an oxide interface and review the physical properties observed at low temperature upon carrier density modulation achieved by field effect. We analyze magnetoresistance curves measured at different temperatures within the theory of weak localization in the presence of spin-orbit to uncover the strength of the Rashba coupling.
