Simulations of metastable decay in two- and three-dimensional models with microscopic dynamics
M. A. Novotny, P. A. Rikvold, M. Kolesik +2
We present a brief analysis of the crossover phase diagram for the decay of a metastable phase in a simple dynamic lattice-gas model of a two-phase system. We illustrate the nuclea…
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…
Kinetic Ising System in an Oscillating External Field: Stochastic Resonance and Residence-Time Distributions
S. W. Sides, R. A. Ramos, P. A. Rikvold +1
Experimental, analytical, and numerical results suggest that the mechanism by which a uniaxial single-domain ferromagnet switches after sudden field reversal depends on the field m…
Response of Kinetic Ising System to Oscillating External Fields: Amplitude and Frequency Dependence
S. W. Sides, R. A. Ramos, P. A. Rikvold +1
The S=1/2, nearest-neighbor, kinetic Ising model has been used to model magnetization switching in nanoscale ferromagnets. For this model, earlier work based on the droplet theory…
