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...

By taking into account two types of boundary conditions (BC), free boundary condition (FBC) and zero boundary condition (ZBC), an improved transverse Ising model with the consideration of surface transition layers (STL) is used to describe the polarization properties of ferroelectric thin films...

For chemical solution decomposition process, the precursor solution is a basic factor affecting the quality of the deposited-film. In this paper, we choose (l00)-oriented 0.7[(Bi0.95Ce0.05)0.5Na0.5(Ti0.99Fe0.01)O3]-0.3BiFe0.97Mn0.03O3(0.7NBTCeFe-0.3BFOMn) thin films prepared by various precursor...

Within the framework of the modified Ginzburg–Landau–Devonshire phenomenological theory, we study the properties of a ferroelectric thin film with surface transition layer, considering the effect of electrodes. The combined effect of the electrode and surface transition layer on the...

The (100)-oriented Ca0.4Sr0.6Bi4Ti4O15(C0.4S0.6BTi) thin film was successfully prepared by a sol-gel method on Pt/Ti/SiO2/Si substrate. The orientation and formation of thin films under different annealing schedules were studied using XRD and SEM. XRD analysis indicated that (100)-oriented...

La modified CBTi (CLBTi) thin films were prepared on Pt/Ti/SiO2/Si(100) substrates by a sol–gel technique. X-ray diffraction analysis showed that single phase of CLBTi thin films were obtained. Their crystallization and hysteresis behavior were strongly dependent on the La contents. An...

The dynamics of one-dimensional quantum spin systems has been a long standing theoretical and experimental problem. Among them, the transverse Ising model with multi-spin interactions, regarded as one of the simplest with non-trivial dynamics, has attracted considerable interest in recent years....

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 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...
