Pattern recognition with nanoscale oscillators

Abstract

Spin Torque Nano Oscillators are nanometric devices that turn polarized electrical current into magnetic oscillations via the spin transfer torque effect. These nanometric oscillators present non-linear behavior between amplitude and frequency resulting in synchronization with external perturbations or other oscillators. These properties, as well as the dependency of their characteristic oscillation with the current applied makes them very suitable candidates to be the physical hard-ware for artificial neural networks
