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…
Large-angle, gigahertz-rate random telegraph switching induced by spin-momentum transfer
Matthew R. Pufall, William H. Rippard, Shehzaad Kaka +4
We show that spin-polarized dc current passing through a small magnetic element induces two-state, random telegraph switching of the magnetization via the spin-momentum transfer ef…
