High-Velocity Magnetic Domain Wall Motion Driven by Acoustic Spin Transfer Torque
Jiacheng Lu, Fa Chen, Yiming Shu +6
We predict high-velocity magnetic domain wall (DW) motion driven by out-of-plane acoustic spin in surface acoustic waves (SAWs). We demonstrate that the SAW propagating at a 30-deg…

Nonreciprocally Boosting Magnetoacoustic Coupling with Surface-Acoustic-Wave-induced Spin Transfer Torque
Shuting Cui, Fa Chen, Liyang Liao +6
Strengthening magnetoacoustic coupling is crucial to the improvement of the surface acoustic wave (SAW)-driven spintronics devices. A key challenge in enhancing magnetoacoustic cou…
