Rashba自旋-轨道耦合涌现电感的本征和非本征可调谐性

Intrinsic and extrinsic tunability of Rashba spin-orbit coupled emergent inductors

Jun'ichi Ieda, Yuta Yamane

摘要:

提出的螺旋磁体的涌现感应[Jpn. J. Appl. Phys. 58,120909(2019)]和最近证明的[Nature 586,232(2020)]被证明通过全面处理Rashba自旋轨道耦合和电子自旋弛豫来进一步扩展,这些耦合和弛豫影响自旋转移力矩和自旋动力的基本过程。在绝热近似下,我们发现,输出电压的广泛改变,通过Rashba效应的内在,而通过非绝热修正由于自旋弛豫和样品无序的extraperitance。研究结果分别阐明了通过电选通和仔细的样品制备可调谐的涌现电感的幅度调制和符号变化的起源。

英文摘要:

The emergent induction of spiral magnets that was proposed [Jpn. J. Appl. Phys. 58, 120909 (2019)] and recently demonstrated [Nature 586, 232 (2020)] is shown to be further extended by a comprehensive treatment of the Rashba spin-orbit coupling and the electron spin relaxation that affect the underlying processes of spin-transfer torque and spinmotive force. Within adiabatic approximation, we show that the output voltages are widely altered intrinsically via the Rashba effect whereas extrinsically via the nonadiabatic correction due to the spin relaxation and sample disorder. The findings respectively clarify the origins for the amplitude modulation and sign change of the emergent inductance with tunability by electrical gating and careful sample preparation.
