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 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 (∞).

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
