Abrupt Enhancement of Spin-Orbit Scattering Time in Ultrathin Semimetallic SrIrO${}_3$ Close to the Metal-Insulator Transition

L. Zhang, X. Jiang, X. Xu +1

We report a magnetotransport study of spin relaxation in 1.4-21.2 nm epitaxial SrIrO${}_3$ thin films coherently strained on SrTiO${}_3$ substrates. Fully charge compensated semimetall…
