Lattice-driven magnetoresistivity and metal-insulator transition in single-layered iridates
Lattice-driven magnetoresistivity and metal-insulator transition in single-layered iridates
Sr2IrO4 exhibits a novel insulating state driven by spin-orbit interactions. We report two novel phenomena, namely a large magnetoresistivity in Sr2IrO4 that is extremely sensitive to the orientation of magnetic field but exhibits no apparent correlation with the magnetization, and a robust metallic state that is induced by dilute electron …
