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…

Stochastic spin-orbit-torque synapse and its application in uncertainty quantification
Cen Wang, Guang Zeng, Xinyu Wen +5
Stochasticity plays a significant role in the low-power operation of a biological neural network. In an artificial neural network (ANN), stochasticity also contributes to critical…
