Structural and Magnetic Properties of Pt/Co/Mn-Based Multilayers
Martin Lonsky, Myoung-Woo Yoo, Yi-Siou Huang +3
Magnetic multilayers are a rich class of materials systems with numerous highly tunable physical parameters that determine both their magnetic and electronic properties. Here we pr…
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…
Analytical model of the inertial dynamics of a magnetic vortex
Myoung-Woo Yoo, Francesca Mineo, Joo-Von Kim
We present an analytical model to account for the inertial dynamics of a magnetic vortex. The model is based on a deformation of the core profile based on the Döring kinetic field,…
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,…
Modulation and phase-locking in nanocontact vortex oscillators
Jérémy Létang, Sébastien Petit-Watelot, Myoung-Woo Yoo +4
We have conducted experiments to probe how the dynamics of nanocontact vortex oscillators can be modulated by an external signal. We explore the phase-locking properties in both th…
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…
