摘要：

The critical behaviour of a magnetic superlattice is examined within the framework of the effective field theory with correlations. For a spin-1/2 Ising model of superlattice is obtained the general formalism of phase transition temperature T-c derivation. The transition temperatures of the alternating superlattice are calculated as a function of the film thickness and the inter- and intralayer exchange constants. The effects of surface modification are also studied numerically.
