The Site‐Bond Diluted Transverse Ising Model with S = 1

Chuan‐Zhang Yang, Jialin Zhong

Published May 1, 1989• 26 citations
Publisher

Abstract

Abstract Within the framework of an effective‐field theory, the longitudinal and transverse magnetization, critical temperature, and critical transverse field of a site‐bond diluted transverse Ising ferromagnet on square lattice with S = 1 are calculated in detail. The dependence of these thermodynamic quantities on the concentration of the sites and of the bonds is investigated.

The Bond‐Diluted Spin‐1 Transverse Ising Model with Random Longitudinal Field

A. Benyoussef, Hamid Ez-zahraouy A

Abstract The bond‐dilution effects on the phase diagram of a spin‐1 king ferromagnet in a transverse field with random longitudinal field is investigated within an expansion technique for cluster identities of spin‐ localized spin systems. Longitudinal and transverse magnetizations are studied for several values of thc bond concentration. The critical temperature dependence on the bond concentration, the longitudinal field, and the transverse field are presented. General formulae applicable to structurcs with arbitrary coordination number N are given.

Thermodynamical Properties of the Diluted Transverse Ising Model with Anisotropic Coupling Constants

J. A. Plascak

Abstract The thermodynamical properties of the site‐ and bond‐diluted transverse Ising model with anisotropic coupling constants are studied by using a variational procedure based on Bogolyubov's inequality. Within this approach the thermal behaviour of the system is obtained in the entire range of temperature (0 ≤ T < ∞). The results for the critical temperature, critical transverse field, and critical concentration are, in several cases, comparable to the constant‐coupling approximation.

The diluted transverse Ising model

T. Kaneyoshi

Two effective-field treatments are presented for the diluted transverse Ising model. The methods include the effects of correlation. The critical temperature, the longitudinal and transverse magnetisations, the initial transverse susceptibility and the two-site spin correlation function are calculated for a square lattice. It was found that, in particular, the transverse magnetisation and the initial transverse susceptibility exhibit behaviour which is interesting in the diluted case.

A New Type of Bond‐Dilution Problem in a Ferromagnetic Insulator with a Fractional Random Coordination Number

Enaldo F. Sarmento, Heber R. da Cruz, T. Kaneyoshi

Abstract The ferromagnetic phase stability limits (or phase diagrams) of a quenched bond‐diluted spin‐ ½ transverse Ising ferromagnetic insulator with a fractional random coordination number are studied within the framework of the effective‐field theory with correlations. The changes of transition temperature and critical concentration with the topology of the network (or the averaged connectivity) are examined in the zero transverse field. The results obtained are compared with those available in the literature. The influences of transverse field on the critical frontiers are also obtained.

Critical properties of a random transverse crystal field Ising model with bond dilution

Ling Wen, Yan Shi-Lei

Abstract Within effective field theory (EFT), the critical properties of a random transverse crystal field Ising model with bond dilution are studied on a square lattice. Under both weak and strong bond dilution conditions, we consider three cases (α = 0,±0.5) of a transverse crystal field ratio, obtaining global phase diagrams in T−D x space for changes in the random transverse crystal field concentration. The phase diagrams obtained for a weak bond dilution are very similar in shape to those of pure bond but with decreases in corresponding ordered phases and critical values. However, the phase diagrams for a strong bond dilution exhibit varieties, including a change in reentrant phenomenon, the occurrence of transverse crystal field degeneration, and the opposite direction crossover of temperature peak value.
