Magnetic properties of a ferromagnetic thin film with four spin interaction: A Monte Carlo simulation study
2013 (English)In: Journal of Magnetism and Magnetic Materials, ISSN 0304-8853, Vol. 339, 127-132 p.Article in journal (Refereed) Published
Monte Carlo simulation has been used to study the critical behaviors and the magnetic properties of a ferromagnetic thin Ising film with a plaquette four spin interaction. The effects of the ratio r(s) =J(s)/J of the surface exchange interaction to the bulk one and the four spin interaction on phase diagrams are investigated. A number of characteristic behaviors have been found, which include the first-and second-order phase transitions, thus also the tricritical points, triple point and isolated critical point.
