โœฆ Synopsis

Within the framework of the effective-field theory with correlations, the ferromagnetic spin-2 Ising model with a transverse crystal field on honeycomb, square and simple cubic lattices is studied. We have investigated the effect of the transverse crystal field on the phase diagrams, magnetization, quadrupolar moments, internal energy and specific heat of the system. The tricritical phenomena have been observed in our system.

The critical properties of a ferroelectric multilayer system consisting of two alternating different pseudo spin-1/2 and spin-S (S ! 1/2) ferroelectric slabs with the same thickness L are discussed by the use of the spin-S transverse Ising model. The behavior of the transition temperature T c and th
