Abstract: We investigate the spin-dependent transport properties of a two-dimensionalelectron gas formed at oxides- interface in the presence of a magnetic field.We consider several scenarios for the oxides- properties, including oxides withco-linear or spiral magnetic and ferroelectric order. For spiral multiferroicoxides, the magnetoelectric coupling and the topology of the localized magneticmoments introduce additional, electric field controlled spin-orbit couplingthat affects the magneto-oscillation of the current. An interplay of thisspin-orbit coupling, the exchange field, and of the applied magnetic fieldresults in a quantum, gate-controlled spin and charge Hall conductance.
