Abstract
Within the framework of the effective field theory, we examine the pha se transitions in a spin-1/2 Ising model of an alternating magnetic su perlattice. We calculate the critical temperature of the alternating s uperlattice as a function of the intralayer and interlayer exchange in teractions and the film thickness. The effects of modified surface lay ers on the critical temperature are also considered.
