Single-spin spectroscopy of spontaneous and phase-locked spin torque oscillator dynamics
Adrian Solyom, Michael Caouette-Mansour, Brandon Ruffolo +3
We employ N- magnetometry to measure the stray field dynamics of a ferromagnetic permalloy nanowire driven by spin-orbit torques. Specifically, we observe the optically detected…
Implementation of a Binary Neural Network on a Passive Array of Magnetic Tunnel Junctions
Jonathan M. Goodwill, Nitin Prasad, Brian D. Hoskins +9
The increasing scale of neural networks and their growing application space have produced demand for more energy- and memory-efficient artificial-intelligence-specific hardware. Av…
Immunity of nanoscale magnetic tunnel junctions to ionizing radiation
Eric Arturo Montoya, Jen-Ru Chen, Randy Ngelale +9
Spin transfer torque magnetic random access memory (STT-MRAM) is a promising candidate for next generation memory as it is non-volatile, fast, and has unlimited endurance. Another…
A quasi-linear spin-torque nano-oscillator via enhanced negative feedback of power fluctuations
O. J. Lee, P. M. Braganca, V. S. Pribiag +2
We report an approach to improving the performance of spin torque nano-oscillators (STNOs) that utilizes power-dependent negative feedback to achieve a significantly enhanced dynam…
Enhancement in spin-torque efficiency by nonuniform spin current generated within a tapered nanopillar spin valve
P. M. Braganca, O. Ozatay, A. G. F. Garcia +3
We examine the effect a spatially non-uniform spin current with a component polarized partially out of the plane has on a low saturation magnetization nanomagnet free layer. Microm…
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…
