C. Moron et M. Mora, MONTE-CARLO SIMULATION OF DOMAIN GROWTH-KINETICS IN THE Q-STATE FERROMAGNETIC POTTS-MODEL, Journal of magnetism and magnetic materials, 177, 1998, pp. 169-170
A Monte Carlo procedure is applied to the study of the kinetics of low
and high-Q Potts models on surfaces quenched from a high temperature
(T much greater than T-c) to low temperatures (T < T-c). The kinetics
of these models are analyzed in simulations which yield the time depen
dence of the size and shape of the domains. Pinning effects in systems
with Q greater than or equal to 3 lead to extremely slow kinetics for
particular domain geometries. Low-temperature quenches on a triangula
r lattice indicate that these pinned geometries are rarely nucleated,
while quenches on a square lattice equilibrate much mon slowly due to
pinning. (C) 1998 Elsevier Science B.V. All rights reserved.
