Spin-Torque Ferromagnetic Resonance Measurements of Damping in Nanomagnets
G. D. Fuchs, J. C. Sankey, V. S. Pribiag +8
We measure the magnetic damping parameter a in thin film CoFeB and permalloy (Py) nanomagnets at room temperature using ferromagnetic resonance driven by microwave frequency spin-t…
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…
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…
