摘要：

We examine the effect of antisite disorder on the magnetic properties of Sr2FeMoO6 by means of Monte Carlo simulation of a physically reasonable model that takes into account the origin of the ferromagnetic interactions between Fe ions. With this model, the main experimental features found in these compounds are recovered by the simulations. Special attention has been paid to the study of the critical properties as a function of disorder. The critical exponents beta and gamma calculated from the simulations are consistent with experiment.
