Abstract
In this paper, we study the magnetic order-disorder layering transitions in a polyamidoamine (PAMAM) dendrimer nanostructure, under the effect of a variable crystal field. This PAMAM dendrimer nanostructure is found in many scientific domains. Firstly, we examine the magnetic properties of this model consisting of the spin S=1 Ising ferromagnetic model in real nanostructure. At null temperature\(\thinspace \left (T\mathrm {=0} \right )\), we give and discuss the ground-state phase diagrams in different planes. For non-null temperature values, we applied the Monte Carlo simulations showing interesting results, summarized in different phase diagrams. We also examined the effect of the coupling exchange interactions on the order-disorder layering transitions of the studied system.
