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…
Current-Induced Nanomagnet Dynamics for Magnetic Fields Perpendicular to the Sample Plane
S. I. Kiselev, J. C. Sankey, I. N. Krivorotov +5
We present electrical measurements of high-frequency magnetic dynamics excited by spin-polarized currents in Co/Cu/Ni80Fe20 nanopillar devices, with a magnetic field applied perpen…
Reduction of spin transfer by synthetic antiferromagnets
N. C. Emley, F. J. Albert, E. M. Ryan +5
Synthetic antiferromagnetic layers (SAF) are incorporated into spin transfer nanopillars giving a layer composition [Co(bottom)/Ru/Co(fixed)]/Cu/Co(free), where square brackets ind…
