Low frequency noise characteristics of sub-micron magnetic tunnel junctions

B. Zhong, Y. Chen, S. Garzon +2

We report that low frequency (up to 200 kHz) noise spectra of magnetic tunnel junctions with areas ~10^{-10}cm^2$ at 10 Kelvin deviate significantly from the typical 1/f behavior f…

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…

Effect of resistance feedback on spin torque-induced switching of nanomagnets

Samir Garzon, Richard A. Webb, Mark Covington +2

In large magnetoresistance devices spin torque-induced changes in resistance can produce GHz current and voltage oscillations which can affect magnetization reversal. In addition,…

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…
