Reversal Modes of Simulated Iron Nanopillars in an Obliquely Oriented Field
S. H. Thompson, G. Brown, P. A. Rikvold
Stochastic micromagnetic simulations are employed to study switching in three-dimensional magnetic nanopillars exposed to highly misaligned fields. The switching appears to proceed…
FORC Analysis of homogeneous nucleation in the two-dimensional kinetic Ising model
D. T. Robb, M. A. Novotny, P. A. Rikvold
The first-order reversal curve (FORC) method is applied to the two-dimensional kinetic Ising model. For the system size and magnetic field chosen, the system reverses by the homoge…
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…
Projective Dynamics in Realistic Models of Nanomagnets
S. H. Thompson, G. Brown, P. A. Rikvold
The free-energy extrema governing the magnetization-reversal process for a model of an iron nanopillar are investigated using the projective dynamics method. Since the time evoluti…
A Biological Coevolution Model with Correlated Individual-Based Dynamics
Volkan Sevim, Per Arne Rikvold
We study the effects of interspecific correlations in a biological coevolution model in which organisms are represented by genomes of bitstrings. We present preliminary results for…
Low-temperature nucleation in a kinetic Ising model under different stochastic dynamics with local energy barriers
Gloria M. Buendia, Per Arne Rikvold, Kyungwha Park +1
Using both analytical and simulational methods, we study low-temperature nucleation rates in kinetic Ising lattice-gas models that evolve under two different Arrhenius dynamics tha…
