▎ 摘 要
In this paper, we study the magnetic properties and the effect of the Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions in a bilayer graphene structure with non-equivalent planes of a ferromagnetic consisting of the spins sigma = 1 / 2 and S = 1. The studied system is formed by two magnetic planes (A and B), separated by a number of non-magnetic planes. In fact, the influence of the coupling exchange interactions, the external magnetic field, and the crystal field is investigated and presented as well as the ground-state phase diagrams. Using Monte Carlo simulations, we examine the behavior of the magnetizations and the total magnetization as a function of the values of system parameters. The effect of the RKKY interactions increases for increasing values of the number of non-magnetic planes; for this reason, the studied system becomes disorder when the number of non-magnetic planes increased. When the susceptibility peaks correspond to the reduced critical temperature (T / J (A)), this critical temperature is displaced towards the lower temperatures.
