Abstract

Based on the Monte Carlo method, the relative variances of magnetization Rm and susceptibility Rχ in the disordered spin lattice Ising model are computed as a function of the degree of the dilution of a disorder. It is shown that the introduction of a disorder in the form of nonmagnetic impurities in the three-dimensional Ising model produces nonzero values for Rm and Rχ at the critical point.
