Abstract In this present work, we study the magnetic properties of the polymer nano-systems involving a core-shell structure. In fact, we investigate the effects of the external magnetic field, the anisotropy effect, the exchange coupling interactions and the temperature in order to explicit the magnetic properties of these polymer nano-structure systems. On the other hand, we examine the existence of the compensation temperature induced by the presence of the core-shell structure. Firstly, we present the ground state phase diagrams, in different planes of the physical parameters. On the other hand, we applied the Monte Carlo simulations, at non null temperature values, in order to investigate the thermal behavior of such nano-structure systems. To complete this study, we investigate the anisotropy crystalline effect on the partial and total magnetizations.
