Abstract

Abstract Within the framework of the effective‐field theory with correlations, a spin‐$ {3 \over 2} $ transverse Ising model in the longitudinal random‐field on a honeycomb lattice is studied. The phase diagrams and the behavior of the tricritical point are examined. The possible re‐entrance phenomena displayed by the system due to the competition effects that occur for the appropriate ranges of the random and transverse field are investigated. The longitudinal and transverse magnetizations, the longitudinal quadrupolar moments and internal energy are given numerically for a honeycomb lattice (z = 3). (© 2004 WILEY‐VCH Verlag GmbH & Co.

Phase diagrams and tricritical behavior of a diluted spin-1 transverse Ising model in a random field

Enaldo F. Sarmento, T. Kaneyoshi

Phase diagrams and magnetization curves of a diluted spin-1 transverse Ising model in a random field on honeycomb, square, and simple-cubic lattices, respectively, are investigated by the use of an effective-field theory with correlations. The tricritical point is found in the system, in contrast to the corresponding spin-1/2 Ising counterpart. The behavior of the tricritical point is also examined as a function of applied transverse field. The possible reentrant phenomena displayed by the system due to the competition effects that occur for appropriate ranges of the random and transverse fields are investigated.

Phase Diagram and Tricritical Behavior of a Spin-2 Transverse Ising Model in a Random Field

Yaqiu Liang, Guozhu Wei, Song Li-Li +2 more

The phase diagrams of a spin-2 transverse Ising model with a random field on honeycomb, square, and simple-cubic lattices, respectively, are investigated within the framework of an effective-field theory with correlations. We find the behavior of the tricritical point and the reentrant phenomenon for the system with any coordination number z , when the applied random field is bimodal. The behavior of the tricritical point is also examined as a function of applied transverse field. The reentrant phenomenon comes from the competition between the transverse field and the random field.

Thermodynamical Properties of Spin-3/2 Ising Model in a Longitudinal Random Field with Crystal Field

Yaqiu Liang, Guozhu Wei, Zhang Hong +1 more

A theoretical study of a spin-3/2 Ising model in a longitudinal random field with crystal field is studied by using of the effective-field theory with correlations. The phase diagrams and the behavior of the tricritical point are investigated numerically for the honeycomb lattice when the random field is bimodal. In particular, the specific heat and the internal energy are examined in detail for the system with a crystal-field constant in the critical region where the ground-state configuration may change from the spin-3/2 state to the spin-1/2 state. We find many interesting phenomena in the system.

Spin‐1 Random‐Bond Transverse Ising Model with Competing Interactions

Chuan‐Zhang Yang, Jialin Zhong, Xue‐Fan Jiang

Abstract The longitudinal magnetization, the transverse magnetization, and the order parameter y of the spin‐1 random‐bond transverse Ising model with competing interactions on a diamond lattice are discussed within the framework of the effective‐field theory. The phase diagrams of the system are obtained. The possible reentrant phenomena displayed by the system and the influence of random parameters α and p̄ on the behavior of the system are investigated.

Magnetic Properties of Transverse Ising Model under a Time Oscillating Longitudinal Field

Xiaoling Shi, Li Wang, Guozhu Wei

A transverse Ising spin system, in the presence of time-dependent longitudinal field, is studied by the effective-field theory (EFT). The effective-field equations of motion of the average magnetization are given for the simple cubic lattice (Z = 6) and the honeycomb lattice (Z = 3). The Liapunov exponent λ is calculated for discussing the stability of the magnetization and it is used to determine the phase boundary. The dynamic phase transition diagrams in h 0 /ZJ — Γ/ZJ plane and in h 0 /ZJ — T/ZJ plane have been drawn, and there is no dynamical tricritical point on the dynamic phase transition boundary. The effect of the thermal fluctuations upon the dynamic phase boundary has been discussed.
