Towards mutual synchronization of serially connected Spin Torque Oscillators based on magnetic tunnel junctions
Piotr Rzeszut, Jakub Mojsiejuk, Witold Skowroński +4
Multiple neuromorphic applications require the tuning of two or more devices to a common signal. Various types of neuromorphic computation can be realized using spintronic oscillat…
Spin-torque Dynamics for Noise Reduction in Vortex-based Sensors
Mafalda Jotta Garcia, Julien Moulin, Steffen Wittrock +12
Performance of magnetoresistive sensors is today mainly limited by their 1/f low-frequency noise. Here, we study this noise component in vortex-based TMR sensors. We compare the no…
Step-like dependence of memory function on pulse width in spintronics reservoir computing
Terufumi Yamaguchi, Nozomi Akashi, Kohei Nakajima +3
Physical reservoir computing is a type of recurrent neural network that applies the dynamical response from physical systems to information processing. However, the relation betwee…
Periodic structure of memory function in spintronics reservoir with feedback current
Terufumi Yamaguchi, Nozomi Akashi, Sumito Tsunegi +3
The role of the feedback effect on physical reservoir computing is studied theoretically by solving the vortex-core dynamics in a nanostructured ferromagnet. Although the spin-tran…
Influence of flicker noise and nonlinearity on the frequency spectrum of spin torque nano-oscillators
Steffen Wittrock, Philippe Talatchian, Sumito Tsunegi +12
The correlation of phase fluctuations in any type of oscillator fundamentally defines its spectral shape. However, in nonlinear oscillators, such as spin torque nano oscillators, t…
Binding events through the mutual synchronization of spintronic nano-neurons
Miguel Romera, Philippe Talatchian, Sumito Tsunegi +9
The brain naturally binds events from different sources in unique concepts. It is hypothesized that this process occurs through the transient mutual synchronization of neurons loca…
