Abstract

Spin-orbit interaction in solids can be utilized for controlling spin-dependent transport phenomena. To realize them, we focus on thin films and interfaces of iridium (Ir) oxides since electron conduction there is dominated by 5d electrons with strong spin-orbit interaction. The first example is the inverse spin Hall effect, which converts a spin current into an electric voltage. The performance of IrO₂ as a spin-current detector is better than those of noble metals. The second is the topological Hall effect originating from magnetic skyrmions. The epitaxial bilayers consisting of SrRuO₃ and SrIrO₃ enable us to generate skyrmions through artificially broken inversion symmetry at the interfaces. These results can be a step toward future spintronics.
