The Deformed Image Vortex Ansatz: A Perturbation-Aware Description of Magnetic Vortices in In-Plane Fields
Thomas G. Coppée, Colin Ducarme, Simon de Wergifosse +1
Thiele-based descriptions of magnetic vortex dynamics in thin ferromagnetic nanodots rely on magnetization ansätze that describe the equilibrium texture but cannot represent pertur…
Spintronics for image recognition: performance benchmarking via data-driven simulations
Anatole Moureaux, Chloé Chopin, Simon de Wergifosse +2
We present a demonstration of image classification using an extreme learning machine (ELM) based on a unique simulated magnetic tunnel junction (MTJ) delayed in time. As the ground…
Neuromorphic spintronics simulated using an unconventional data-driven Thiele equation approach
Anatole Moureaux, Simon de Wergifosse, Chloé Chopin +1
In this study, we developed a quantitative description of the dynamics of spin-torque vortex nano-oscillators (STVOs) through an unconventional model based on the combination of th…
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)…
Neuromorphic spintronics accelerated by an unconventional data-driven Thiele equation approach
Anatole Moureaux, Simon De Wergifosse, Chloé Chopin +2
We design a neural network based on a single spin-torque vortex nano-oscillator (STVO) multiplexed in time. The behavior of the STVO is simulated with an improved ultra-fast and qu…
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…
