摘要

A Monte Carlo simulation is conducted to investigate the magnetic characteristics and magnetocaloric effect of the Ising model on a diluted graphene-like monolayer in this research. It is obtained that temperature-dependent dynamic order parameters, magnetic susceptibility, critical temperature, magnetic entropy, and RCP are strongly influenced by key physical parameters such as temperature (T), atomic concentration (P), crystal field (D), external magnetic field (h₀), additive bias field (hb), and its angular frequency (ω). It is indicated that decreasing P and increasing h0 can significantly enhance the change in magnetic entropy and RCP. These results might provide an important theoretical basis for future applications of diluted graphene.
