Using the replica exchange algorithm, we calculate the temperature dependence of various physical quantities of interest including the overlap and the Binder parameters. We observe a transition between a paramagnetic phase and a spin-glass phase and estimate the critical temperature for the phase transition to be T∼4.0(1) in units of J∕kB, where J is the coupling strength between spins and kB is the Boltzmann constant. Using the scaling behavior of the Binder parameter, we estimate the scaling exponent to be ν∼1.10(2).en©2006 The American Physical SocietyJournal article002006093510.1103/PhysRevB.73.2244190002386963000652-s2.0-3374515102152614Leinweber, D.
