Mutual control of stochastic switching for two electrically coupled superparamagnetic tunnel junctions
Philippe Talatchian, Matthew W. Daniels, Advait Madhavan +5
Superparamagnetic tunnel junctions (SMTJs) are promising sources for the randomness required by some compact and energy-efficient computing schemes. Coupling SMTJs gives rise to co…
Flicker and random telegraph noise between gyrotropic and dynamic C-state of a vortex based spin torque nano oscillator
Steffen Wittrock, Philippe Talatchian, Miguel Romera +8
Vortex based spin torque nano oscillators (STVOs) can present more complex dynamics than the spin torque induced gyrotropic (G) motion of the vortex core. The respective dynamic mo…
Beyond the gyrotropic motion: dynamic C-state in vortex spin torque oscillators
Steffen Wittrock, Philippe Talatchian, Miguel Romera Rabasa +9
In the present study, we investigate a dynamical mode beyond the gyrotropic (G) motion of a magnetic vortex core in a confined magnetic disk of a nano-pillar spin torque nano oscil…
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…
