Bifurcation analysis of strongly nonlinear injection locked spin torque oscillators
J. Hem, L. D. Buda-Prejbeanu, U. Ebels
We investigate the dynamics of an injection locked in-plane uniform spin torque oscillator for several forcing configurations at large driving amplitudes. For the analysis, the spi…
Simultaneous memory effects in the stress and in the dielectric susceptibility of a stretched polymer glass
J. Hem, C. Crauste-Thibierge, Clement Florence +2
We report experimental evidence that a polymer stretched at constant strain rate presents complex memory effects after that is set to zero at a specific strain $λ_w…
Relaxation time of a polymer glass stretched at very large strains
R. Sahli, J. Hem, C. Crauste-Thibierge +3
The polymer relaxation dynamic of a sample, stretched up to the stress hardening regime, is measured, at room temperature, as a function of the strain for a wide range of the s…
Frequency shift keying by current modulation in a MTJ-based STNO with high data rate
A. Ruiz-Calaforra, A. Purbawati, T. Brächer +9
Spin torque nano-oscillators are nanoscopic microwave frequency generators which excel due to their large frequency tuning range and agility for amplitude and frequency modulation.…
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…
