Antisymmetric magnetoresistance of the SrTiO 3/LaAlO 3 interface

S Seri, L. Klein

Research output: Contribution to journalArticlepeer-review


The longitudinal resistance Rxx of the SrTiO3/LaAlO3 interface with magnetic fields applied perpendicular to the interface has an antisymmetric term [namely, Rxx(H)≠Rxx(−H)] which increases with decreasing temperature and increasing field. We argue that the origin of this phenomenon is a nonhomogeneous Hall effect with clear contribution of an extraordinary Hall effect, suggesting the presence of nonuniform field-induced magnetization.
