Gate voltage modulation of spin-Hall-torque-driven magnetic switching
Luqiao Liu, Chi-Feng Pai, D. C. Ralph +1
Two promising strategies for achieving efficient control of magnetization in future magnetic memory and non-volatile spin logic devices are spin transfer torque from spin polarized…
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-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…
X-ray photoemission study of CoFeB/MgO thin film bi-layers
J. C. Read, P. G. Mather, R. A. Buhrman
We present results from an X-ray photoemission spectroscopy (XPS) study of CoFeB/MgO bi-layers where we observe process-dependent formation of B, Fe, and Co oxides at the CoFeB/MgO…
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…
