Frequency shift keying in vortex-based spin torque oscillators
M. Manfrini, T. Devolder, Joo-Von Kim +4
Vortex-based spin-torque oscillators can be made from extended spin valves connected to an electrical nanocontact. We study the implementation of frequency shift keying modulation…

Theory of the power spectrum of spin-torque nanocontact vortex oscillators
Joo-Von Kim, Thibaut Devolder
Spin-transfer torques in magnetic nanocontacts can lead to self-sustained magnetization oscillations that involve large-amplitude gyrotropic vortex motion. This dynamics consists o…

Direct experimental measurement of phase-amplitude coupling in spin torque oscillators
L. Bianchini, S. Cornelissen, Joo-Von Kim +4
We study spin-torque induced oscillations of MgO magnetic tunnel junctions in the time domain. By using the Hilbert transform on the time traces, we obtain for the first time a dir…
