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…
Thermal conductivity of amorphous and crystalline GeTe thin film at high temperature: Experimental and theoretical study
Kanka Ghosh, Andrzej Kusiak, Pierre Noé +2
Thermal transport properties bear a pivotal role in influencing the performance of phase change memory (PCM) devices, in which the PCM operation involves fast and reversible phase…
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…
Spin transfer driven resonant expulsion of a magnetic vortex core for efficient rf detector
Samh Menshawy, Alex Jenkins, Karla J Merazzo +7
Spin transfer magnetization dynamics have led to considerable advances in Spintronics, including opportunities for new nanoscale radiofrequency devices. Among the new functionaliti…
Ultra-fast perpendicular Spin Orbit Torque MRAM
Murat Cubukcu, Olivier Boulle, Nikolaï Mikuszeit +14
We demonstrate ultra-fast (down to 400 ps) bipolar magnetization switching of a three-terminal perpendicular Ta/FeCoB/MgO/FeCoB magnetic tunnel junction. The critical current densi…
Temperature dependence of the emission linewidth in MgO-based spin torque nano-oscillators
J. F. Sierra, M. Quinsat, U. Ebels +8
Spin transfer driven excitations in magnetic nanostructures are characterized by a relatively large microwave emission linewidth (10 -100 MHz). Here we investigate the role of ther…
Enhancement of the electronic contribution to the low temperature specific heat of Fe/Cr magnetic multilayer
B. Revaz, M. -C. Cyrille, B. Zink +2
We measured the low temperature specific heat of a sputtered magnetic multilayer, as well as separate thick Fe and Cr films. Magnetoresistance an…
