Simulation Studies of Nanomagnet-Based Architecture
David Carlton, Nathan Emley, Eduard Tuchfeld +1
We report a simulation study on interacting ensembles of Co nanomagnets that can perform basic logic operations and propagate logic signals, where the state variable is the magneti…
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…
Large-amplitude coherent spin waves exited by spin-polarized current in nanoscale spin valves
I. N. Krivorotov, D. V. Berkov, N. L. Gorn +4
We present spectral measurements of spin-wave excitations driven by direct spinpolarized current in the free layer of nanoscale Ir20Mn80/Ni80Fe20/Cu/Ni80Fe20 spin valves. The measu…
Time-Resolved Spin Torque Switching and Enhanced Damping in Py/Cu/Py Spin-Valve Nanopillars
N. C. Emley, I. N. Krivorotov, A. G. F. Garcia +4
We report time-resolved measurements of current-induced reversal of a free magnetic layer in Py/Cu/Py elliptical nanopillars at temperatures T = 4.2 K to 160 K. Comparison of the d…
Mechanisms limiting the coherence time of spontaneous magnetic oscillations driven by DC spin-polarized currents
J. C. Sankey, I. N. Krivorotov, S. I. Kiselev +4
The spin-transfer torque from a DC spin-polarized current can generate highly-coherent magnetic precession in nanoscale magnetic-multilayer devices. By measuring linewidths of spec…
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…
