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...

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 phase diagrams (transition temperature and compensation temperature) and magnetizations of a cylindrical nanowire with a (positive or negative) core–shell interaction and a surface dilution, described by the transverse Ising model (TIM), are investigated by the use of the effective-field...

The magnetic properties of a transverse Ising thin film are investigated by the use of the two theoretical frameworks, namely the standard mean-field theory and the effective field theory better than the mean-field theory. Some new aspects of the magnetic properties have been clarified firstly...

The phase diagram of a ferroelectric thin film described by the transverse Ising model is discussed by the use of the standard mean field approximation and other approximations better than the mean field approximation. Some characteristic features have been observed in the results of mean field...
