Phys. Rev. B 56, 14529–14532 (1997)Single-cluster algorithm for the site-bond-correlated Ising modelReceived 2 June 1997; revised 12 August 1997; published in the issue dated 1 December 1997 We extend the Wolff algorithm to include correlated spin interactions in diluted magnetic systems. This algorithm is applied to study the site-bond-correlated 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 autocorrelation time diminishes in the presence of dilution and correlation, showing that the Wolff algorithm performs even better in such situations. © 1997 The American Physical Society URL:
