摘要:

本文报道了具有Rashba自旋轨道耦合(RSOC)的铁磁(FM)金属中的逆自旋霍尔效应(ISHE)的本征形式,该效应由正常的电荷电流驱动。与传统形式不同,ISHE可以在不需要从外部源注入自旋电流的情况下被诱导。我们的理论结果表明,霍尔电压产生时,FM力矩垂直于铁磁层。霍尔电压的极性在将FM力矩切换到相反方向时被反转,从而有望成为存储器或逻辑应用的有用的回读机制。

英文摘要:

We report an intrinsic form of the inverse spin Hall effect (ISHE) in ferromagnetic (FM) metal with Rashba spin orbit coupling (RSOC), which is driven by a normal charge current. Unlike the conventional form, the ISHE can be induced without the need for spin current injection from an external source. Our theoretical results show that Hall voltage is generated when the FM moment is perpendicular to the ferromagnetic layer. The polarity of the Hall voltage is reversed upon switching the FM moment to the opposite direction, thus promising a useful readback mechanism for memory or logic applications.
