Proximitized magnetotransport at SrVO3/ErCrO3 heterointerface
Abstract
We report on the interfacial magnetotransport properties of a heterostructure composed of non-magnetic metal SrVO3 and magnetic insulator ErCrO3. There can be seen a magnetic proximity effect between these layers represented by the emergence of anomalous Hall effect (AHE) and anisotropic magnetoresistance (AMR). The AHE is not scaled with macroscopic magnetization of ErCrO3 at lower temperatures, suggesting contributions beyond the conventional AHE. The AMR measurements reveal the sensitive response of the magnetotransport properties to the spin textures of ErCrO3, exhibiting two- and fourfold symmetric terms upon azimuthal rotation of magnetic field. These results highlight the potential of utilizing magnetic spin textures of insulating orthorhombic perovskites to explore emergent magnetotransport in adjacent conducting layer at the heterointerface.
