Investigating thermodynamic and magnetic behavior of graphullerene-like nanostructure using Monte Carlo techniques

In the world of carbon-based materials, the effective synthesis of a graphullerene-like nanostructure with remarkable features is a noteworthy accomplishment. This insight holds great promise for advancing the development of a new category of materials. In this study, we examined the thermodynamic characteristics and magnetocaloric effects of a structure resembling graphullerene using Monte Carlo simulations. The current study provides a detailed analysis of how Hamiltonian parameters impact the thermodynamic properties and magnetocaloric quantities of the system. Moreover, our findings indicate that adjusting the magnetic field not only allows for critical regulation of temperature but also has a notable impact on magnetocaloric characteristics. This includes changes in magnetic entropy and the relative cooling capacity. Based on our results, it is strongly suggested that the graphullerene-like nanostructure holds great promise as a candidate for applications in magnetic refrigeration.
