Planar Hall effect and anisotropic magnetoresistance in polar-polar interface of LaVO-KTaO with strong spin-orbit coupling.

Among the perovskite oxide family, KTaO (KTO) has recently attracted considerable interest as a possible system for the realization of the Rashba effect. In this work, we report a novel conducting interface by placing KTO with another insulator, LaVO (LVO) and report planar Hall effect (PHE) and anisotropic magnetoresistance (AMR) measurements. This interface exhibits a signature of strong spin-orbit coupling.
