Parallelization of a Dynamic Monte Carlo Algorithm: a Partially Rejection-Free Conservative Approach
G. Korniss, M. A. Novotny, P. A. Rikvold
We experiment with a massively parallel implementation of an algorithm for simulating the dynamics of metastable decay in kinetic Ising models. The parallel scheme is directly appl…
Simulation of Magnetization Switching in Biaxial Single-Domain Ferromagnetic Particles
Xuekun Kou, M. A. Novotny, Per Arne Rikvold
The magnetization switching dynamics of biaxial single-domain homogeneous ferromagnetic particles, in which the two easy axes are perpendicular to each other, is simulated using a…
Test of the Kolmogorov-Johnson-Mehl-Avrami picture of metastable decay in a model with microscopic dynamics
Raphael A. Ramos, Per Arne Rikvold, M. A. Novotny
The Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory for the time evolution of the order parameter in systems undergoing first-order phase transformations has been extended by Sekimoto…
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…
Magnetic Particles
M. A. Novotny, P. A. Rikvold
We present an overview of the subject of Magnetic Particles, starting at a level suitable for advanced high-school students and ending at a level suitable for current practitioners…
Universality and Scaling for the Structure Factor in Dynamic Order-Disorder Transitions
Gregory Brown, Per Arne Rikvold, Martin Grant
The universal form for the average scattering intensity from systems undergoing order-disorder transitions is found by numerical integration of the Langevin dynamics. The result is…
Monte Carlo Methods for Equilibrium and Nonequilibrium Problems in Interfacial Electrochemistry
Gregory Brown, Per Arne Rikvold, S. J. Mitchell +1
We present a tutorial discussion of Monte Carlo methods for equilibrium and nonequilibrium problems in interfacial electrochemistry. The discussion is illustrated with results from…
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…
Monte Carlo simulation of magnetization reversal via domain-wall motion in Fe sesquilayers on W(110)
M. Kolesik, M. A. Novotny, Per Arne Rikvold
Iron sesquilayers are ultrathin films with coverages between one and two atomic monolayers. They consist of an almost defect-free monolayer with compact islands of a second atomic…
