Abstract
In this work, we study the magnetic properties of a nanostructure based on an hexagonal core-shell geometry. The model is formed with core spins Ï=3/2 and surface spins S=2. More precisely, we investigate the effect of the coupling exchange interactions in the absence/presence of both an external magnetic and crystal fields. In a first step, we elaborate the ground state phase diagrams, and then we discuss the stable phases. At different non null temperatures, we explore Monte Carlo to study computation and the magnetic properties. Among others, we find a compensation temperature between the spins Ï and S. To close this study, we examine the hysteresis loop behaviors.
