Sažetak
The effect of the quenched random dilution on the ferromagnetic transitions, in particular, the conversion from the first- to second-order transition is discussed. The new results are presented for the diluted three-dimensional three-state Potts model. The critical exponents of the disorder-induced second-order phase transition are derived by the finite-size scaling analysis of the moments of the energy and the largest cluster, obtained from the Monte Carlo simulations.
