The critical behavior of a transverse ferromagnet spin-1/2 Ising superlattice

Using the effective field theory that accounts for the self-spin correlatio n function, the critical behavior of a magnetic superlattice consisting of two different ferromagnets is examined in a transverse spin-1/2 Ising model . The dependence of the critical temperature on the thickness of the consti tuents in a unit cell is investigated for different cases. A critical value of the interface exchange coupling above which the interface magnetism app ears is found. The effect of the transverse field on the system Is also inv estigated.
