Selective control of vortex polarities by microwave field in two robustly synchronized spin-torque nano-oscillators
Yi Li, Xavier de Milly, Olivier Klein +3
Manipulating operation states of coupled spin-torque nano-oscillators (STNOs), including their synchronization, is essential for applications such as complex oscillator networks. I…
Vowel recognition with four coupled spin-torque nano-oscillators
Miguel Romera, Philippe Talatchian, Sumito Tsunegi +14
Substantial evidence indicates that the brain uses principles of non-linear dynamics in neural processes, providing inspiration for computing with nanoelectronic devices. However,…
Low-Energy Truly Random Number Generation with Superparamagnetic Tunnel Junctions for Unconventional Computing
Damir Vodenicarevic, Nicolas Locatelli, Alice Mizrahi +10
Low-energy random number generation is critical for many emerging computing schemes proposed to complement or replace von Neumann architectures. However, current random number gene…
Controlling the synchronization properties of two dipolarly coupled vortex based spin-torque nano-oscillators by the intermediate of a third one
Flavio Abreu Araujo, Julie Grollier
In this paper, we propose to control the strength of phase-locking between two dipolarly coupled vortex based spin-torque nano-oscillators by placing an intermediate oscillator bet…
Skyrmion Gas Manipulation for Probabilistic Computing
Daniele Pinna, Flavio Abreu Araujo, Joo-Von Kim +5
The topologically protected magnetic spin configurations known as skyrmions offer promising applications due to their stability, mobility and localization. In this work, we emphasi…
Neuromorphic computing with nanoscale spintronic oscillators
Jacob Torrejon, Mathieu Riou, Flavio Abreu Araujo +10
Neurons in the brain behave as non-linear oscillators, which develop rhythmic activity and interact to process information. Taking inspiration from this behavior to realize high de…
