Mutual control of stochastic switching for two electrically coupled superparamagnetic tunnel junctions
Philippe Talatchian, Matthew W. Daniels, Advait Madhavan +5
Superparamagnetic tunnel junctions (SMTJs) are promising sources for the randomness required by some compact and energy-efficient computing schemes. Coupling SMTJs gives rise to co…
Switching Distributions for Perpendicular Spin-Torque Devices within the Macrospin Approximation
W. H. Butler, T. Mewes, C. K. A. Mewes +4
We model "soft" error rates for writing (WSER) and for reading (RSER) for perpendicular spin-torque memory devices by solving the Fokker-Planck equation for the probability distrib…
Thermal Relaxation Rates of Magnetic Nanoparticles in the Presence of Magnetic Fields and Spin-Transfer Effects
William Rippard, Ranko Heindl, Matthew Pufall +2
We have measured the relaxation time of a thermally unstable ferromagnetic nanoparticle incorporated into a magnetic tunnel junction (MTJ) as a function of applied magnetic field,…
Spin Transfer Dynamics in Spin Valves with Out-of-plane Magnetized CoNi Free Layers
William H. Rippard, Alina M. Deac, Matthew R. Pufall +5
We have measured spin transfer-induced dynamics in magnetic nanocontact devices having a perpendicularly magnetized Co/Ni free layer and an in-plane magnetized CoFe fixed layer. Th…
Time domain measurement of phase noise in a spin torque oscillator
Mark W. Keller, A. B. Kos, T. J. Silva +2
We measure oscillator phase from the zero crossings of the voltage vs. time waveform of a spin torque nanocontact oscillating in a vortex mode. The power spectrum of the phase nois…
