The critical behaviour of the three-dimensional dilute Ising model : universality and the Harris criterion

Abstract
Monte Carlo simulation of quenched site-diluted three-dimensional Ising model has been carried out using the Swendsen-Wang algorithm. The susceptibility exponent and the correlation length exponent are estimated to be γ = 1.52 ± 0.07, v = 0.77 ± 0.04, respectively, for all p c < p < 1, where p is the concentration of the spins. In contrast to some earlier work, our results strongly support the concept of universality
