论文摘要
在理论上预测并研究了旋转大厅效应的轨道效应（OHE），这是旋转大厅效应的轨道效应，并研究了超过十年，但在实验中尚未观察到。在这里，我们提出了一种通过触点的自旋轨道耦合将OHE中的轨道电流转换为旋转电流的策略。此外，我们发现OHE在使用磁性接触时可以诱导大型非偏射磁性。生成的旋转电流和轨道霍尔磁场都可以应用于实验和设计轨道设备中的OHE。
The intrinsic orbital Hall effect (OHE), the orbital counterpart of the spin Hall effect, was predicted and studied theoretically for more than one decade, yet to be observed in experiments. Here we propose a strategy to convert the orbital current in OHE to the spin current via the spin-orbit coupling from the contact. Furthermore, we find that OHE can induce large nonreciprocal magnetoresistance when employing magnetic contact. Both the generated spin current and the orbital Hall magnetoresistance can be applied to probe the OHE in experiments and design orbitronic devices.
