The transverse ferromagnet spin-1/2 Ising model of an alternating magneticsuperlattice

The critical behavior of the transverse ferromagnetic spin-1/2 using model of an alternating magnetic superlattice is examined using the framework of the effective field theory with a probability distribution technique that a ccounts for the self-spin correlation function. The critical temperature of the alternating superlattice is calculated as a function of the intralayer and interlayer exchange interactions, the strength of the transverse field and the film thickness. The effects of modified surface layers on the crit ical temperature of the system are also considered.
