Abstract
We extend the Wolff algorithm to include correlated spin interactions in diluted magnetic systems. This algorithm is applied to study the si te-bond-correlate Ising model on a two-dimensional square lattice.:We use a finite-size scaling procedure to obtain the phase diagram in the temperature-concentration space. We also have verified that the autoc orrelation time diminishes in the presence of dilution and correlation , showing that the Wolff algorithm performs even better in such situat ions.
