Diverse dynamics in interacting vortices systems through tunable conservative and non-conservative coupling strengths
A. Hamadeh, A. Koujok, D. R. Rodrigues +6
Magnetic vortices are highly tunable, nonlinear systems with ideal properties for being applied in spin wave emission, data storage, and neuromorphic computing. However, their tech…
Injection locking in DC-driven spintronic vortex oscillators via surface acoustic wave modulation
R. Moukhader, D. R. Rodrigues, A. Riveros +4
Control of the microwave signal generated by spin-transfer torque oscillators (STOs) is crucial for their applications in spin wave generation and neuromorphic computing. This stud…
Resonant excitation of vortex gyrotropic mode via surface acoustic waves
