Dynamic magnetic properties of the mixed-spin (3/2,5/2) Ising graphene-like monolayer in an oscillating magnetic field are studied by means of Monte Carlo simulation.The effects of Hamiltonian parameters such as crystal field and time-dependent oscillating magnetic field on the dynamic order parameter,susceptibility and internal energy of the system are well presented and explained.Moreover,much attention has also been dedicated to the phase diagrams with different parameters in order to better comprehend the impacts of these parameters on the critical temperature.Our results reveal that the crystal fields of two sublattices have similar effects on the critical temperature,but the bias field and amplitude of oscillating field have opposite effects on it.We hope that our research can be of guiding significance to the theoretical and experimental studies of graphene-like monolayer.
