Transistor behavior via Au clusters etched from electrodes in an acidic gating solution: metal nanoparticles mimicking conducting polymers
Jacob E. Grose, Burak Ulgut, Abhay N. Pasupathy +2
We report that the electrical conductance between closely-spaced gold electrodes in acid solution can be turned from off [insulating; I] to on [conducting; C] to off again by monot…
Mechanically-adjustable and electrically-gated single-molecule transistors
A. R. Champagne, A. N. Pasupathy, D. C. Ralph
We demonstrate a device geometry for single-molecule electronics experiments that combines both the ability to adjust the spacing between the electrodes mechanically and the abilit…
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…
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…
