Synchronization of spin torque oscillators through spin Hall magnetoresistance
arXiv:1705.04386 · doi:10.1109/TMAG.2017.2704588
Abstract
Spin torque oscillators placed onto a nonmagnetic heavy metal show synchronized auto-oscillations due to the coupling originating from spin Hall magnetoresistance effect. Here, we study a system having two spin torque oscillators under the effect of the spin Hall torque, and show that switching the external current direction enables us to control the phase difference of the synchronization between in-phase and antiphase.
