Abstract
The nonequilibrium and equilibrium behavior of the two-dimensional Ising model are studied after rapid cooling in a random field. Extensive Monte Carlo simulations are presented, covering a wide range of temperature and random-field strength. Quantitative comparison is made with several recent theories of domain growth and equilibration. In particular, strong support is given to the Villain-Grinstein-Fernandez theory of logarithmic growth.Keywords
