We present results from extensive numerical simulations of phase ordering dynamics in a mean-field dynamical model of weakly disordered random magnets. We apply a stringent test of dynamical scaling to confirm that the domain growth is superuniversal, i.e., the scaling function for the...

The dilute Ising model with a p = 0.8 fraction of the sites occupied by spins is simulated on L3 systems for L up to 300, using a single-cluster algorithm of Wolff. In the range of reduced temperature 0.002(T − Tc)/Tc0.03 the susceptibility appears to fit a simple power with an effective...
