Phase diagrams of kekulene-like nanostructure

Kekulene-like nanostructure is described by Ising model with anisotropy. Effective field theory with correlations is employed to study phase diagrams and magnetization of the system. The numerical results show the physical parameters, such as anisotropy and exchange couplings, have important effects on magnetic properties. Various types of phase diagrams and reentrant phase transition exhibit, which are sensitive of anisotropy and exchange coupling. Studying the phase transition of this structure could help to further understand new kekulene-like family.
