Abstract
By means of Monte Carlo simulation, we have explored the magnetic and thermodynamic behaviors of the diluted ferromagnetic spin-3/2 Ising nano-graphene monolayer under the longitudinal magnetic field. The effects of the number of lattice sites, magnetic atom concentration, crystal field and external longitudinal magnetic field on the magnetic phase transition and hysteresis behaviors of the present system have been discussed. The characteristic curves of magnetization, magnetic susceptibility, internal energy and the specific heat as a function of temperature have been displayed specifically. We have presented the phase diagrams for various physical parameters. It is found that the area, coercivity and remanence of the hysteresis loops are strongly dependent on those selected parameters.
