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

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 mean-field and high temperature series expansion (HTSE) combined with the Padé approximant calculations. The scaling law of magnetic susceptibility and magnetization is used to determine the critical exponent γ, ν _eff (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 (∞).
