Time-Domain Studies of Very-Large-Angle Magnetization Dynamics Excited by Spin Transfer Torques
I. N. Krivorotov, N. C. Emley, R. A. Buhrman +1
We describe time-domain measurements which provide new information about the large-angle nonlinear dynamics of nanomagnets excited by spin-transfer torque from a spin-polarized cur…
Spin-transfer-driven ferromagnetic resonance of individual nanomagnets
J. C. Sankey, P. M. Braganca, A. G. F. Garcia +3
We demonstrate a technique that enables ferromagnetic resonance (FMR) measurements of the normal modes for magnetic excitations in individual nanoscale ferromagnets, smaller in vol…
Spin-Transfer Excitations of Permalloy Nanopillars for Large Applied Currents
S. I. Kiselev, J. C. Sankey, I. N. Krivorotov +4
Using measurements of the spectra of microwave-frequency resistance oscillations, we determine the phase diagram of magnetic excitations caused by torques from DC spin-polarized cu…
Adjustable spin torque in magnetic tunnel junctions with two fixed layers
G. D. Fuchs, I. N. Krivorotov, P. M. Braganca +4
We have fabricated nanoscale magnetic tunnel junctions (MTJs) with an additional fixed magnetic layer added above the magnetic free layer of a standard MTJ structure. This acts as…
Spin-Transfer Effects in Nanoscale Magnetic Tunnel Junctions
G. D. Fuchs, N. C. Emley, I. N. Krivorotov +7
We report measurements of magnetic switching and steady-state magnetic precession driven by spin-polarized currents in nanoscale magnetic tunnel junctions with low-resistance, < 5…
Temperature dependence of spin-transfer-induced switching of nanomagnets
I. N. Krivorotov, N. C. Emley, A. G. F. Garcia +4
We measure the temperature, magnetic-field, and current dependence for the switching of nanomagnets by a spin-polarized current. Depending on current bias, switching can occur betw…
