Abstract

In this paper, we inspect the magnetic properties of a core/shell Kekulene-like structure consisting of mixed spins (σ = 2; S = 1), by means of Monte Carlo simulations. Firstly, we carry out an analysis of the ground state phase diagrams to determine all probable and stable configurations depending on the minimization of the energies of the system. Furthermore, the magnetizations and susceptibilities as a function of temperature are obtained with the effect of the crystal field and the exchange coupling interactions of the system. To conclude, we discuss the hysteresis loops as a function of the external magnetic field.
