Description

Within the framework of an effective field theory with correlations, it was investigated the effects of surface single ion anisotropy on the surface phase transition of a semi-infinite Ising model with a spin-one free surface. Behavior characteristic of surface magnetism is found, and comparison is made with standard molecular field results. (A.C.A.S.)

Abstract (Portuguese)

Dentro de um modelo de teoria de campo efetivo com correlacoes, investigamos os efeitos de uma anisotropia uniaxial de superficie na transicao de fase de superficie de um meio semi-infinito (Ising) com uma superficie livre de spins-1. Algumas caracteristicas de magnetismo de superficie sao encontrads e os resultados sao comparados com aqueles fornecidos pela teoria de campo medio. (autor)
