Abstract

In this paper,a renormalization group scheme within the framework of the mean field theory is used to investigate the critical behavior at the surface of a semi infinite Ising system with mixed spins,i.e.S=1 at the surface and σ=1/2 in the bulk.The effects of a random field on the surface phase diagrams are obtained.

We use the mean field renormalization group method to treat the semi-infinite Ising ferromagnetic system with the amorphization of the surface. The critical behavior of the surface with a surface random field, including critical temperature, the possibility of tricritical and reentrant phenomena, are investigated in detail.

Mean-field renormalization-group approaches to the surface on a semi-infinite Ising model with a random surface field

Gang Sun

We study the critical behavior of the surface on a semi-infinite simple-cubic-lattice Ising model with a bimodal random surface field by a large-cell mean-field renormalization-group method. Our results show that a surface ferromagnetic phase exists at weak random fields above the bulk critical temperature, and no signs of the tricritical point are found until the surface critical temperature decreases to that of the bulk.

The critical behavior of both semi-infinite spin-1/2 Ising system and spin-1/2 Ising film in a random transverse surface field has been studied within an effective field theory. The effect of the ratio R of the surface exchange interaction to the bulk one, random transverse surface field and film thickness on the phase diagrams are investigated.

Mean-field theory of the semi-infinite spin-1/2 Ising model with random surface and bulk fields

M. Saber

All the possible phase diagrams of a three-dimensional semi-infinite spin-1/2 Ising model in a random field as a function of the ratio of bulk and surface interactions and the ratio of bulk and surface fields have been determined. Within the framework of the mean-field approximation eight generic types of phase diagrams can be found. It is also shown that such a system can exhibit a variety of phase transitions and multi-critical points.

Phase Diagram of the Semi-Infinite Ising Model in a Random Field

A.S. de Arruda, W. Figueiredo

We determine the phase diagram of the semi-infinite Ising model in a cubic lattice with a trimodal distribution of random fields on the surface. We use the mean-field renormalization group with the smallest possible clusters to show that a very small dilution of the random field at surface is sufficient to destroy the tricritical behavior.

Numerical Calculations for the Surface on a Semi-Infinite Ising Model with a Random Surface Field

Gang Sun, Jie Yang

We study the critical behavior of the surface on a semi-infinite simple cubic lattice Ising model with a bimodal random surface field by large cell mean-field renormalization group method and Monte Carlo simulations. Our results show that the surface ferromagnetic phase exists in the weak random field range above the bulk critical temperature. The surface specific heat is not divergence and the susceptibility show a cusp singularity at the surface ferromagnetic-paramagnetic transition for a relatively large random field.
