▎ 摘 要
Using the Monte Carlo method, the ferrimagnetic mixed-spin (3/2, 5/2) Ising model is proposed to research the physical properties of graphene cluster monolayer, such as magnetization, susceptibility, internal energy, specific heat and hysteresis loops. The phase diagrams are also gained to investigate the blocking temperature T-B and the discontinuous point T-K under the different parameters. The abundant multi-loop hysteresis characteristics are observed, such as quintuple-loop, triple-loop and double-loop, owing to the competition among various parameters.
