Abstract

A definition of the average size R of the domains observed during a first-order phase transition, which is based on the time-dependent excess internal energy is introduced. The temperature dependence of the growth law for R(t,T), where t is time and T is the quench temperature, has been investigated over a wide range of temperature below and near Tc, in the two-dimensional spin-flip Ising model. The results obtained support the Allen-Cahn growth law, R(t,T)2(T)t, and allow an estimate of the temperature dependence of the nonuniversal coefficient (T). Nonmonotonic behavior of is observed at low temperature, which is attributed to lattice anisotropy.
