自旋和电荷自由度之间的相互作用提供了一个强大的工具来操纵存储器中的磁化由电流诱导的自旋轨道扭矩。这种新的现象，传统上存在于半导体和金属系统，最近已被观察到在过渡金属氧化物，表现出令人惊讶的大自旋霍尔角。在这篇文章中，我们将回顾过渡金属氧化物中自旋-电荷转换的最新研究进展，剩余的挑战和新的机遇。我们将首先简要总结最近的进展，在代表性的过渡金属氧化物，包括SrIrO 3，SrRuO 3，和IrO 2，沿着与其他材料的计算预测的自旋-电荷转换。接下来，我们将调查过渡金属氧化物家族中可能的候选材料。沿着综述了SrIrO 3薄膜生长的最新进展及其对自旋霍尔效应研究的影响。我们也将讨论其他有希望的候选人，可以作为自旋源，包括薄膜烧绿石和铜铁矿氧化物以及氧化物异质结构。(c)2021年作者。除非另有说明，否则所有文章内容均根据知识共享署名（CC BY）许可证（http：//creativecommons.org/licenses/by/4.0/）进行许可。
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 in semiconductors and metallic systems, has recently been observed in transition metal oxides, exhibiting a surprising large spin-Hall angle. In this Perspective, we will review recent research progress in the spin-charge conversion in transition metal oxides, the remaining challenges, and new opportunities. We will first briefly summarize recent progress in the spin-charge conversion in representative transition metal oxides, including SrIrO3, SrRuO3, and IrO2, along with other materials predicted by calculations. Next, we will survey the possible candidate materials in the family of transition metal oxides. Recent advances in the growth of SrIrO3 films will be reviewed along with the implications on the study of the spin-Hall effect. We will also discuss other promising candidates that could serve as the spin source, including films of pyrochlore and delafossite oxides as well as oxide heterostructures. (c) 2021 Author(s).
