Mean-field and high temperature series expansion calculations of some magnetic properties of Ising and XY antiferromagnetic thin-films

Abstract

In this work, the magnetic properties of Ising and XY antiferromagnetic thin-films are investigated each as a function of Néel temperature and thickness for layers (n = 2, 3, 4, 5, 6, and bulk (∞)) by means of a mean-field and high temperature series expansion (HTSE) combined with Padé approximant calculations. The scaling law of magnetic susceptibility and magnetization is used to determine the critical exponent γ, νeff (mean), ratio of the critical exponents γ/ν, and magnetic properties of Ising and XY antiferromagnetic thin-films for different thickness layers n = 2, 3, 4, 5, 6, and bulk (∞).
