Spin momentum transfer and Oersted field induce a vortex nano-oscillator in thin ferromagnetic film devices
M. A. Hoefer, T. J. Silva
A nonlinear model of spin-wave excitation involving a point contact in a thin ferromagnetic film that includes the Oersted magnetic field contribution is presented. We consider the…

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…
