Stabilization of phase noise in spin torque nano oscillators by a phase locked loop
Steffen Wittrock, Martin Kreißig, Bertrand Lacoste +10
The main limitation in order to exploit spin torque nano-oscillators (STNOs) in various potential applications is their large phase noise. In this work, we demonstrate its efficien…
Magnetic oscillations Excited by Concurrent Spin Injection from a Tunneling Current and a Spin Hall Current
M. Tarequzzaman, T. Böhnert, M. Decker +9
In this paper, a 3-terminal spin-transfer torque nano-oscillator (STNO) is studied using the concurrent spin injection of a spin-polarized tunneling current and a spin Hall current…
Injection locking at 2f of spin torque oscillators under influence of thermal noise
M. Tortarolo, B. Lacoste, J. Hem +7
Experiments, numerical simulations and an analytic model were developed to elucidate the effects of noise in the synchronized state of a tunnel junction based spin torque nano osci…
Synthetic ferrimagnet spin transfer torque oscillator: model and non-linear properties
Bertrand Lacoste, Miguel Romera, Ursula Ebels +1
The non-linear parameters of spin-torque oscillators based on a synthetic ferrimagnet free layer (two coupled layers) are computed. The analytical expressions are compared to macro…
Spin torque driven dynamics of a coupled two layer structure: interplay between conservative and dissipative coupling
M. Romera, B. Lacoste, U. Ebels +1
In this manuscript the general concepts of spin wave theory are adapted to the dynamics of a self-polarized system based on two layers coupled via interlayer exchange (conservative…
Modulating spin transfer torque switching dynamics with two orthogonal spin-polarizers by varying the cell aspect ratio
B. Lacoste, M. Marins de Castro, T. Devolder +9
We study in-plane magnetic tunnel junctions with additional perpendicular polarizer for subnanosecond-current-induced switching memories. The spin-transfer-torque switching dynamic…
