摘要：
By establishing Ising model, we investigated the thermodynamic properties and magnetocaloric effect of a diluted Kekulene-like structure with defects. Under the influence of different exchange coupling and the concentration of magnetic atoms, the changes in some magnetic and thermodynamic quantities including the magnetocaloric effect were discussed. For the change of concentration and exchange coupling, which parameter is more crucial to the magnetic properties of the structure was also given. The results indicate that when the exchange coupling and the concentration of magnetic atoms increase, the temperature range corresponding to the entropy change becomes wider. Besides, the relative cooling power (RCP) increases as the exchange coupling decreases or the concentration of magnetic atoms increases.
