Abstract: The critical coupling and spontaneous magnetization curve for the 2D-Ising model are calculated using the effective-field method with correlations. An application of the method to the quantum S = 1/2 1D-Heisenberg model is presented and reliable low-temperature estimates of the specific heat are evaluated.
