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…
Quantized spin wave modes in magnetic tunnel junction nanopillars
A. Helmer, S. Cornelissen, T. Devolder +4
We present an experimental and theoretical study of the magnetic field dependence of the mode frequency of thermally excited spin waves in rectangular shaped nanopillars of lateral…
Current-driven vortex oscillations in metallic nanocontacts: Zero-field oscillations and training effects
M. van Kampen, L. Lagae, G. Hrkac +4
We present an experimental and theoretical study of the low-field dynamics of current-driven vortex oscillations in nanocontacts based on spin-valve multilayers. These oscillations…
Direct current control of three magnon scattering processes in spin-valve nanocontacts
H. Schultheiss, F. Ciubotaru, A. Laraoui +9
We have investigated the generation of spin waves in the free layer of an extended spin-valve structure with a nano-scaled point contact driven by both microwave and direct electri…
