Abstract

In This work, we apply the Monte Carlo simulations to study the magnetic properties and compensation behavior of a core/shell double fullerene structure X_60 where the symbol X can be assigned to any magnetic atom. We focus our study on a system formed by a double sphere forming a core-shell. The two spheres are containing the spins: S=1/2 in the core; and {\sigma}=1 in the shell, respectively. In a first step, we investigate and discuss the corresponding ground state phase diagrams in different planes. Also, we illustrated the behavior of the magnetizations and the effect of the coupling exchange interactions as well as the crystal field. The effect of the external magnetic field, and the exchange coupling interactions on the hysteresis loops have been inspected. To complete this study, we showed the existence of the compensation temperature for the studied system.
