Auto-oscillation threshold and line narrowing in MgO-based spin-torque oscillators
S. Cornelissen, L. Bianchini, G. Hrkac +7
We present an experimental study of the power spectrum of current-driven magnetization oscillations in MgO tunnel junctions under low bias. We find the existence of narrow spectral…
Lineshape distortion in a nonlinear auto-oscillator near generation threshold: Application to spin-torque nano-oscillators
Joo-Von Kim, Q. Mistral, C. Chappert +2
The lineshape in an auto-oscillator with a large nonlinear frequency shift in the presence of thermal noise is calculated. Near the generation threshold, this lineshape becomes str…
Current-driven vortex oscillations in metallic nanocontacts
Q. Mistral, M. van Kampen, G. Hrkac +6
We present experimental evidence of sub-GHz spin-transfer oscillations in metallic nano-contacts that are due to the translational motion of a magnetic vortex. The vortex is shown…
Current-driven microwave oscillations in current perpendicular-to-plane spin-valve nanopillars
Q. Mistral, Joo-Von Kim, T. Devolder +5
We study the current and temperature dependences of the microwave voltage emission of spin-valve nanopillars subjected to an in-plane magnetic field and a perpendicular-to-plane cu…
