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…
Role of non-linear data processing on speech recognition task in the framework of reservoir computing
Flavio Abreu Araujo, Mathieu Riou, Jacob Torrejon +8
The reservoir computing neural network architecture is widely used to test hardware systems for neuromorphic computing. One of the preferred tasks for bench-marking such devices is…
Magnetic control of flexible thermoelectric devices based on macroscopic 3D interconnected nanowire networks
Flavio Abreu Araujo, Tristan da Câmara Santa Clara Gomes, Luc Piraux
Spin-related effects in thermoelectricity can be used to design more efficient refrigerators and offer novel promising applications for the harvesting of thermal energy. The key ch…
Probing phase coupling between two spin-torque nano-oscillators with external source
Yi Li, Xavier de Milly, Flavio Abreu Araujo +4
Phase coupling between auto-oscillators is central for achieving coherent responses such as synchronization. Here we present an experimental approach to probe it in the case of two…
Efficient Synchronization of Dipolarly Coupled Vortex-Based Spin Transfer Nano-Oscillators
N. Locatelli, A. Hamadeh, F. Abreu Araujo +10
Due to their nonlinear properties, spin transfer nano-oscillators can easily adapt their frequency to external stimuli. This makes them interesting model systems to study the effec…
