Weak (anti)localization in NdTiO<sub>3</sub>/SrTiO<sub>3</sub> Heterointerfaces

ORAL

Abstract

The quasi-two-dimensional interfacial electron gas formed at complex oxide interfaces exhibits a wide range of interesting physical properties including spin-orbit coupling and magnetism. We report magneto-transport studies on NdTiO3/SrTiO3heterostructures grown by hybrid molecular beam epitaxy. The magneto-transport behavior exhibits a systematic crossover between weak antilocalization and weak localization with changing temperature. The weak-antilocalization analysis of the magnetoresistance provides information about the spin and phase relaxation mechanisms and may indicate the interplay between the interfacial magnetism and spin-orbit coupling.
