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…
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…
Sub-ns spin-transfer switching: compared benefits of free layer biasing and pinned layer biasing
T. Devolder, C. Chappert, K. Ito
We analyze the statistical distribution of switching durations in spin-transfer switching induced by current steps, and discuss biasing strategies to enhance the reproducibility of…
Distribution of the magnetization reversal duration in sub-ns spin-transfer switching
T. Devolder, C. Chappert, J. A. Katine +2
We study the distribution of switching times in spin-transfer switching induced by sub-ns current pulses in pillar-shaped spin-valves. The pulse durations leading to switching foll…
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…
Precessional switching of thin nanomagnets: analytical study
T. Devolder, C. Chappert
We study analytically the precessional switching of the magnetization of a thin macrospin. We analyze its response when subjected to an external field along its in-plane hard axis.…
