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…
Chaotic dynamics in a macrospin spin-torque nano-oscillator with delayed feedback
Jérôme Williame, Artur Difini Accioly, Damien Rontani +2
A theoretical study of delayed feedback in spin-torque nano-oscillators is presented. A macrospin geometry is considered, where self-sustained oscillations are made possible by spi…
