Determination of the basic timescale in kinetic Monte Carlo simulations by comparison with cyclic-voltammetry experiments
I. Abou Hamad, P. A. Rikvold, G. Brown
While kinetic Monte Carlo simulations can provide long-time simulations of the dynamics of physical and chemical systems, it is not yet possible in general to identify the inverse…
Finite-Temperature Micromagnetics of Hysterisis for Misaligned Single Iron Nanopillars
M. A. Novotny, S. M. Stinnett, G. Brown +1
We present micromagnetic results for the hysterisis of a single magnetic nanopillar which is misaligned with respect to the applied magnetic field. We provide results for both a on…
Fine-grid Simulations of Thermally Activated Switching in Nanoscale Magets
G. Brown, M. A. Novotny, P. A. Rikvold
Numerical integration of the Landau-Lifshitz-Gilbert equation with thermal fluctuations is used to study the dynamic response of single-domain nanomagnets to rapid changes in the a…
Hysteresis in an Electrochemical System: Br Electrodeposition on Ag(100)
S. J. Mitchell, G. Brown, P. A. Rikvold
We examine hysteresis in cyclic voltammetry of Br electrosorption onto single-crystal Ag(100) by dynamic Monte Carlo simulations. At room temperature, this system displays a second…
Computer Simulations of Thermal Switching in Small-grain Ferromagnets
M. A. Novotny, G. Brown, P. A. Rikvold
We present Monte Carlo and Langevin micromagnetic calculations to investigate thermal switching of single-domain ferromagnetic particles. For the Monte Carlo study we place particu…
Hard Simulation Problems in the Modeling of Magnetic Materials: Parallelization and Langevin Micromagnetics
G. Korniss, G. Brown, M. A. Novotny +1
We present recent results on two attempts at understanding and utilizing large-scale simulations of magnetic materials. In the first study we consider massively parallel implementa…
