Mutual synchronization of spin-torque oscillators consisting of perpendicularly magnetized free layers and in-plane magnetized pinned layers
Tomohiro Taniguchi, Sumito Tsunegi, Hitoshi Kubota
A mutual synchronization of spin-torque oscillators coupled through current injection is studied theoretically. Models of electrical coupling in parallel and series circuits are pr…
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,…
Relaxation time and critical slowing down of a spin-torque oscillator
Tomohiro Taniguchi, Takahiro Ito, Sumito Tsunegi +2
The relaxation phenomena of spin-torque oscillators consisting of nanostructured ferromagnets are interesting research targets in magnetism. A theoretical study on the relaxation t…
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…
