▎ 摘　　要

Monte Carlo simulation has been used to study magnetization plateaus and thermodynamic properties of the sandwich-like nano-graphene with mixed spin-3/2 and spin-5/2 in a longitudinal magnetic field. The effects of the single-ion anisotropy, the intralayer and interlayer exchange couplings as well as the longitudinal magnetic field on the magnetization, internal energy and specific heat of the system are discussed in detail. Multiple magnetization plateaus behaviors at low temperatures have been found, originating from the competition among various physical parameters. In particular, the results show that the anisotropy, exchange coupling and longitudinal magnetic field play significant roles in controlling the internal energy and specific heat of the system.
