Abstract
ABSTRACTIn this paper, the magnetic properties of a bi-layer nano-stanene like structure with RKKY (Ruderman-Kittel-Kasuya-Yoshida) interactions have been studied using Monte Carlo simulations. The considered system is composed of two magnetic planes with mixed spins σ = 7/2 and S = 1, separated by the non-magnetic planes (L). Firstly, the ground state phase diagrams for zero temperature are reported and discussed. Secondly, for non-zero temperature, we examine the effect of the RKKY interactions on the magnetic properties of our system. It is found that the value of the blocking temperature increases when decreasing the number of the non-magnetic layers. Furthermore, the effect of the exchange coupling interactions on the blocking temperature behavior are investigated. Finally, the effect of several physical parameters on the hysteresis cycles have been determined.
