Abstract
Based on Monte Carlo simulation, we studied the thermodynamic characteristics and magnetocaloric effect of a diluted graphdiyne monolayer with defects. The changes of magnetization, magnetic susceptibility and internal energy induced by physical parameters were examined. In particular, the effects of crystal field, external magnetic field and defect concentration on magnetic entropy change, adiabatic temperature change and hysteresis behavior were studied in detail. In addition, we also gave the relative cooling power induced by different external magnetic field and defect concentration. Finally, we found that defect concentration, temperature and crystal field have similar effect on hysteresis loops.
