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,…
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 transfer switching of spin valve nanopillars using nanosecond pulsed currents
Shehzaad Kaka, Matthew Pufall, William Rippard +4
Spin valve nanopillars are reversed via the mechanism of spin momentum transfer using current pulses applied perpendicular to the film plane of the device. The applied pulses were…
Frequency Modulation of Spin-Transfer Oscillators
M. R. Pufall, W. H. Rippard, S. Kaka +2
Spin-polarized dc electric current flowing into a magnetic layer can induce precession of the magnetization at a frequency that depends on current. We show that addition of an ac c…
