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…
Defects, Tunneling, and EPR Spectra of Single-Molecule Magnets
Kyungwha Park, M. A. Novotny, N. S. Dalal +5
We examine theoretically electron paramagnetic resonance (EPR) lineshapes as functions of resonance frequency, energy level, and temperature for single crystals of three different…
MCAMC: An Advanced Algorithm for Kinetic Monte Carlo Simulations: from Magnetization Switching to Protein Folding
M. A. Novotny, Shannon M. Wheeler
We present the Monte Carlo with Absorbing Markov Chains (MCAMC) method for extremely long kinetic Monte Carlo simulations. The MCAMC algorithm does not modify the system dynamics.…
Dynamics of Magnetization Reversal in Models of Magnetic Nanoparticles and Ultrathin Films
Per Arne Rikvold, Gregory Brown, Steven J. Mitchell +1
We discuss numerical and theoretical results for models of magnetization switching in nanoparticles and ultrathin films. The models and computational methods include kinetic Ising…
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…
Introduction to the Propp-Wilson Method of Exact Sampling for the Ising Model
Mark A. Novotny
An introduction to the Propp-Wilson method of coupling-from-the-past for the Ising model is presented. It enables one to obtain exact samples from the equilibrium spin distribution…
