Time domain detection of pulsed spin torque damping reduction
Longfei Ye, Samir Garzon, Richard A. Webb +3
Combining multiple ultrafast spin torque impulses with a 5 nanosecond duration pulse for damping reduction, we observe time-domain precession which evolves from an initial 1 ns dur…
Macrospin model of incubation delay due to the field-like spin transfer torque
Samir Garzon, Yaroslaw Bazaliy, Richard A. Webb +3
We show that the absence of pre-switching oscillations ("incubation delay") in magnetic tunnel junctions can be explained within the macrospin model by a sizable field-like compone…
Coherent control of nanomagnet dynamics via ultrafast spin torque pulses
Samir Garzon, Longfei Ye, Richard A. Webb +3
The magnetization orientation of a nanoscale ferromagnet can be manipulated using an electric current via the spin transfer effect. Time domain measurements of nanopillar devices a…
Spin momentum transfer in current perpendicular to the plane spin valves
M. Covington, A. Rebei, G. J. Parker +1
We present experimental and numerical micromagnetic data on the effect of spin momentum transfer in current perpendicular to the plane spin valves. Starting from a configuration wi…
Current induced magnetization dynamics in current perpendicular to the plane spin valves
M. Covington, M. AlHajDarwish, Y. Ding +2
We observe magnetization dynamics induced by spin momentum transfer in the noise spectra of current perpendicular to the plane giant magnetoresistance spin valves. The dynamics are…
