The phase diagrams of a superlattice composed from two different alternating ferroelectric slabs with the same thickness L are discussed on the basis of the spin-1/2 transverse Ising model. The two theoretical frameworks of the differential operator technique are applied to the investigations,...

The temperature dependence of the longitudinal magnetization as well as the longitudinal susceptibility of a ferroelectric superlattice described by a transverse spin-12 Ising model are studied using the effective field theory with a probability distribution technique that accounts for the...

The pyroelectric properties and the Curie temperature of a ferroelectric/ferroelectric superlattice with two alternative layers are studied for the transverse Ising model using the effective field theory with a probability distribution technique. The pyroelectric coefficient of bulk materials...

Critical properties (transition temperature and critical transverse field) of a spin-12 Ising superlattice in transverse fields consisting of alternating two different slabs with same thickness L are investigated by the use of the effective-field theory. When the transverse field and the...
