Time-resolved spin-torque switching in MgO-based perpendicularly magnetized tunnel junctions
T. Devolder, Joo-Von Kim, F. Garcia-Sanchez +5
We study ns scale spin-torque-induced switching in perpendicularly magnetized tunnel junctions (pMTJ). Although the switching voltages match with the macrospin instability threshol…
A skyrmion-based spin-torque nano-oscillator
F. Garcia-Sanchez, J. Sampaio, N. Reyren +2
A model for a spin-torque nano-oscillator based on the self-sustained oscillation of a magnetic skyrmion is presented. The system involves a circular nanopillar geometry comprising…
The nature of domain walls in ultrathin ferromagnets revealed by scanning nanomagnetometry
J. -P. Tetienne, T. Hingant, L. J. Martinez +13
The recent observation of current-induced domain wall (DW) motion with large velocity in ultrathin magnetic wires has opened new opportunities for spintronic devices. However, ther…
Understanding nanoscale temperature gradients in magnetic nanocontacts
Sébastien Petit-Watelot, Ruben Miguel Otxoa, Mauricio Manfrini +4
We determine the temperature profile in magnetic nanocontacts submitted to the very large current densities that are commonly used for spin-torque oscillator behavior. Experimental…
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…
