摘要：

Using the finite cluster approximation (FCA) based on a single-site cluster theory and Monte Carlo simulation (MCS) under the Metropolis algorithm, we study the critical properties of two-dimensional (2D) spins-1/2 system by analyzing the effect of the anisotropic parameter a and next-nearest-neighbor (NNN) interaction J '' on the critical temperature T-C of the 2D anisotropic square lattice. It is found that the MCS is more reliable than the FCA method in the resolution of the Ising model. Moreover, MC calculations reveal that Tc is strongly correlated with the external magnetic field h, a, and J '', where the competition between these parameters can generate several rich phase diagrams.
