Abstract

In this work, we investigate a nano-system built on a hexagonal dendrimer structure, for mixed spins σ = 2 and S = 3/2. First, we study this system in the presence/absence of both an external and crystal magnetic fields. The study of the effect of the coupling exchange interactions and the determination of the ground state phase diagrams are discussed. On the other hand, we focus our interest on the study and determination of these parameters. The elaboration and the discussion of all the stable phases have been outlined. A theoretical study by Monte Carlo simulations (MCS) in the framework of the Ising model is used to find out the understanding of the magnetic properties of this system. The obtained results by means of MCS simulations are the critical temperature and the compensation temperature. For fixed values of the coupling exchange interactions and temperature, the hysteresis loop is established, in order to complete this study.
