Abstract
The Fullerene C18 is one of the most active types of nanostructures used as an active ingredient in several applications. This study used Monte Carlo simulations to investigate the magnetic properties of mixed 3/2 and 2 in the fullerene C18 systems. We first perform a theoretical analysis of the ground state phase diagrams. Indeed, we only present and analyze more stable configurations among all possible configurations. Second, calculations were performed to determine how the compound's magnetic properties changed when various physical parameters were altered. In addition, we provide studies of the magnetic behavior of the system at reduced temperature, reduced crystal fields, reduced exchange coupling interactions, and reduced external magnetic fields. Finally, we study and discuss the critical lowering temperature of fullerene C18. To conclude this study, we examined the different hysteresis loops when varying the values of the different physical parameters.
