Spin–charge conversion in transition metal oxides

The interaction between spin and charge degrees of freedom offers a powerful tool to manipulate magnetization in memories by the current induced spin–orbit torque. This novel phenomenon, conventionally existing semiconductors metallic systems, has recently been observed transition metal oxides, exhibiting surprising large spin-Hall angle. In this Perspective, we will review recent research progress spin–charge conversion remaining challenges, new opportunities. We first briefly summarize representative including SrIrO3, SrRuO3, IrO2, along with other materials predicted calculations. Next, survey possible candidate family oxides. Recent advances growth SrIrO3 films be reviewed implications on study effect. also discuss promising candidates that could serve as source, pyrochlore delafossite oxides well oxide heterostructures.
