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…

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…
