Distortion of the Stoner-Wohlfarth astroid by a spin-polarized current
Y. Henry, S. Mangin, J. Cucchiara +2
The Stoner-Wohlfarth astroid is a fundamental object in magnetism. It separates regions of the magnetic field space with two stable magnetization equilibria from those with only on…
Experimental Test of Analytic Theory of Spin Torque Oscillator Dynamics
C. Boone, J. A. Katine, J. R. Childress +3
We make measurements of power spectral density of the microwave voltage emitted by a spin torque nano-oscillator (STNO) and compare our experimental results to predictions of an an…
Bias and angular dependence of spin-transfer torque in magnetic tunnel junctions
C. Wang, Y. -T. Cui, J. Z. Sun +3
We use spin-transfer-driven ferromagnetic resonance (ST-FMR) to measure the spin-transfer torque vector T in MgO-based magnetic tunnel junctions as a function of the offset angle b…
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…
