Abstract

We show that the interplay between spin-orbit coupling and cubic symmetry breaking in SrTiO3 results in a highly anomalous Zeeman effect of conduction electrons substantially different among the three conduction sub-bands and strongly dependent on their splitting. This effect can be measured via electrically-driven spin resonance enabled by the interplay between electron hopping and spin-orbit coupling, and enhanced by the near-degeneracy of the conduction sub-bands. The proposed effects can provide a unique insight into the electronic properties of SrTiO3 and its heterostructures.
