Abstract
Analysis of the high-temperature susceptibility series for the random-field Ising model with a Gaussian distribution of random fields demonstrates the existence of a fluctuation-driven first-order transition below four dimensions, . This, and the behavior of the susceptibility exponent in three dimensions, suggest that is a "critical" dimension for the model.
