论文摘要
从基础科学和设备应用的角度来看，自旋和纳米力学自由度之间的相互作用引起了人们的兴趣。我们研究了铁磁纳米力学悬臂的扭转振荡引起的镁电流。我们发现，有限的Dzyaloshinskii-Moriya（DM）相互作用是由扭转振荡出现的，该扭转振荡被旋转量规场描述，并且DM相互作用导致具有与扭转振荡相同的频率的可检测到的镁电流。我们的理论铺平了使用自旋量规场研究扭转自旋纳米力学现象的道路。
The interaction between spin and nanomechanical degrees of freedom attracts interest from the viewpoint of basic science and device applications. We study the magnon current induced by the torsional oscillation of ferromagnetic nanomechanical cantilever. We find that a finite Dzyaloshinskii-Moriya (DM) interaction emerges by the torsional oscillation, which is described by the spin gauge field, and the DM interaction leads to the detectably-large magnon current with frequency same as that of the torsional oscillation. Our theory paves the way for studying torsional spin-nanomechanical phenomena by using the spin gauge field.
