Hyperchaos in a Magnetic Nanodisk Driven by Ferromagnetic Resonance
A Kolli, Hugo Merbouche, Salvatore Perna +3
We investigate the chaotic dynamics driven in the nonlinear regime of ferromagnetic resonance of an out-of-plane magnetized nanodisk in detail. By combining extensive micromagnetic…
Nanocontact vortex oscillators based on CoMnGe pseudo-spin valves
Jérémy Létang, Claudia de Melo, Charles Guillemard +9
We present an experimental study of vortex dynamics in magnetic nanocontacts based on pseudo spin valves comprising the CoMnGe Heusler compound. The films were grown by molecul…
Pattern generation and symbolic dynamics in a nanocontact vortex oscillator
Myoung-Woo Yoo, Damien Rontani, Jérémy Létang +6
Harnessing chaos or intrinsic nonlinear behaviours from dynamical systems is a promising avenue for the development of unconventional information processing technologies. However,…
Chaos in Magnetic Nanocontact Vortex Oscillators
Thibaut Devolder, Damien Rontani, Sébastien Petit-Watelot +10
We present an experimental study of spin-torque driven vortex self-oscillations in magnetic nanocontacts. We find that above a certain threshold in applied currents, the vortex gyr…
