摘要：
In this work, performing the Monte Carlo simulation, magnetic and thermodynamic properties of a ferromagnetic single layer of spin-3/2 Ising nano-graphene structure have been studied. The exchange interactions, the crystal and the magnetic fields have essential effects on the magnetization, the magnetic susceptibility, the internal energy and on the hysteresis behavior of the system. Interesting phenomena have been obtained. In particular, multiple hysteresis loops have been observed for appropriate parameters of the Hamiltonian.
