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...

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...
