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…
Modeling the spatial resolution of magnetic solitons in Magnetic Force Microscopy and the effect on their sizes
I. Castro, A. Riveros, J. L. Palma +7
In this work, we explored theoretically the spatial resolution of magnetic solitons and the variations of their sizes when subjected to a Magnetic Force Microscopy (MFM) measuremen…
Resonant excitation of vortex gyrotropic mode via surface acoustic waves
A. Koujok, A. Riveros, D. R. Rodrigues +4
Finding new energy-efficient methods for exciting magnetization dynamics is one of the key challenges in magnonics. In this work, we present an approach to excite the gyrotropic dy…
