Deterministic control of the probabilistic phase dynamics in injection-locked spin-torque nano-oscillators
Abderrazak Hakam, Chloé Chopin, Nhat-Tan Phan +8
Spin-torque nano-oscillators (STNOs) inherently exhibit thermally driven phase fluctuations that render their dynamics truly stochastic. Here, we demonstrate that, despite this int…
Current-controlled periodic double-polarity reversals in a spin-torque vortex oscillator
Chloé Chopin, Simon de Wergifosse, Anatole Moureaux +1
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…
A semi-analytical model to simulate the spin-diode effect and accelerate its use in neuromorphic computing
Chloé Chopin, Leandro Martins, Luana Benetti +4
The spin-diode effect is studied both experimentally and with our original semi-analytical method. The latter is based on an improved version of the Thiele equation approach (TEA)…
Memristive and tunneling effects in 3D interconnected silver nanowires
Chloé Chopin, Simon De Wergifosse, Nicolas Marchal +3
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 vo…
Data-driven Thiele equation approach for solving the full nonlinear spin-torque vortex oscillator dynamics
Flavio Abreu Araujo, Chloé Chopin, Simon De Wergifosse
The dynamics of vortex based spin-torque nano-oscillators is investigated theoretically. Starting from a fully analytical model based on the Thiele equation approach, fine-tuned da…
Quantitative and realistic description of the magnetic potential energy of spin-torque vortex oscillators
Simon De Wergifosse, Chloé Chopin, Flavio Abreu Araujo
Understanding the dynamics of magnetic vortices has emerged as an important challenge regarding the recent development of spin-torque vortex oscillators. Either micromagnetic simul…
