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…
Tunable quantum interference between noisy electron sources
Yuanzhen Chen, Samir Garzon, Richard A. Webb
We report shot noise cross correlation measurements in a four terminal beam splitter configuration. By using two tunnel barriers as independent electron sources with tunable statis…
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…
Enhanced Spin Dependent Shot Noise in Magnetic Tunnel Barriers
S. Garzon, Y. Chen, R. A. Webb
We report the observation of enhanced spin dependent shot noise in magnetic tunnel barriers, suggesting transport through localized states within the barrier. This is supported by…
Temperature dependent asymmetry of the nonlocal spin-injection resistance: evidence for spin non-conserving interface scattering
Samir Garzon, Igor Zutic, Richard A. Webb
We report nonlocal spin injection and detection experiments on mesoscopic Co-Al2O3-Cu spin valves. We have observed a temperature dependent asymmetry in the nonlocal resistance bet…
