摘要：

Results of a Monte Carlo simulation appropriate to describe the compound Fe0.25Zn0.75F2 are consistent with spin-glass behavior at zero magnetic field and below the freezing temperature T-f. Binder cumulants, Edwards-Anderson parameter, and non-linear susceptibility, display critical-like behavior near T-f, with exponents in agreement with those of stochastic models.
