Thermodynamic and magnetocaloric properties of an AnB60-n fullerene-like structure under the applied magnetic field

Using Monte Carlo method, we studied the thermodynamic and magnetocaloric properties of an AnB60-n Ising fullerene-like structure under the applied magnetic field. It is emphasized that the importance of the exchange coupling, the applied magnetic field and the atom concentration in controlling various thermodynamic quantities. The temperature dependence of the entropy change and the adiabatic temperature change was further discussed under the effects of different parameters. The refrigeration cooling power (RCP) can be improved through decreasing exchange coupling and increasing the external magnetic field and the atom concentration with greater spin values.
