Using finite-size scaling techniques we compute the critical exponents observing deviations from the pure Ising ones. The differences can be explained as the effects of logarithmic corrections, without requiring to change the Universality Class.engjournal articlehttp://doi.org/10.1088/0305-4470/30/24/006http://iopscience.iop.org/https://arxiv.org/abs/cond-mat/9707179v2open access5351-73Critical-behaviorMonte-CarloImpuritiesSystem.Física (Física)Física-Modelos matemáticos22 Física
