Study demonstrates phase-tunable spin-wave-mediated mutual synchronization of spin Hall nano-oscillators
Schematic representation of in-phase and anti-phase mutual synchronization between SHNOs. Image credit: Akash Kumar. Spin Hall nano-oscillators (SHNOs) are nanoscale spintronic devices that convert direct current into high-frequency microwave signals through spin wave auto-oscillations. This is a type of nonlinear magnetization oscillations that are self-sustained without the need for a periodic external force. Theoretical and
