Current-controlled periodic double-polarity reversals in a spin-torque vortex oscillator
Autor: Chloé Chopin, Simon de Wergifosse, Anatole Moureaux, Flavio Abreu Araujo
Publikováno v: Scientific Reports, Vol 14, Iss 1, Pp 1-6 (2024)
Abstract Micromagnetic simulations are used to study a spin-torque vortex oscillator excited by an out-of-plane dc current. The vortex core gyration amplitude is confined between two orbits due to periodical vortex core polarity reversals. The upper

Ampere–Oersted field splitting of the nonlinear spin-torque vortex oscillator dynamics
Autor: Flavio Abreu Araujo, Chloé Chopin, Simon de Wergifosse
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-8 (2022)
Abstract We investigate the impact of the DC current-induced Ampère–Oersted field on the dynamics of a vortex based spin-torque nano-oscillator. In this study we compare micromagnetic simulations performed using mumax $$^3$$ 3 and our analytical m

Memristive and tunneling effects in 3D interconnected silver nanowires
Autor: Chloé Chopin, Simon de Wergifosse, Nicolas Marchal, Pascal Van Velthem, Luc Piraux, Flavio Abreu Araujo
Publikováno v: ACS Omega, Vol. 8, no.7, p. 6663-6668 (2023)
Due to their memristive properties nanowire networks are very promising for neuromorphic computing applications. Indeed, the resistance of such systems can evolve with the input voltage or current as it confers a synaptic behaviour to the device. Her
