▎ 摘  要

In this paper, we study the magnetic properties of a diluted trilayer graphene structure with non-equivalent planes. The spins of the planes forming the trilayer systems ABA and BAB are S = 1 (for the plane A) and sigma = 3/2 (for the plane B). The ground state phase diagrams are reported and discussed. Besides, we provide the variation of the total magnetizations versus reduced temperature and reduced crystal field for several values of the coupling exchange interactions and the dilution probability, using Monte Carlo simulations. The two systems provide opposite results regarding the compensation temperature T-comp behavior as a function of dilution probability p. Indeed, the compensation temperature increases when decreasing the dilution probability for ABA system. While for the BAB system, T-comp increases when increasing p.
