Super-harmonic injection locking of nano-contact spin-torque vortex oscillators
P. S. Keatley, S. R. Sani, G. Hrkac +4
Super-harmonic injection locking of single nano-contact (NC) spin-torque vortex oscillators (STVOs) subject to a small microwave current has been explored. Frequency locking was ob…

Direct observation of magnetization dynamics generated by nano-contact spin-torque vortex oscillators
P. S. Keatley, S. R. Sani, G. Hrkac +5
Time-resolved scanning Kerr microscopy has been used to directly image the magnetization dynamics of nano-contact (NC) spin-torque vortex oscillators (STVOs) when phase-locked to a…

Agility of vortex-based nanocontact spin torque oscillators
M. Manfrini, T. Devolder, Joo-Von Kim +7
We study the agility of current-tunable oscillators based on a magnetic vortex orbiting around a point contact in spin-valves. Theory predicts frequency-tuning by currents occurs a…
