Abstract
The critical coupling and spontaneous magnetization curve for the 2D-I sing model are calculated using the effective-field method with correl ations. An application of the method to the quantum S = 1/2 1D-Heisenb erg model is presented and reliable low-temperature estimates of the s pecific heat are evaluated.
