摘要: The aim of this study is to determine and interpret the magnetic properties a dendrimer nanoparticle system. In model, we are inspired by system with core-shell spins σ = 3 S 7/2 as elements model. We first examine ground-state phase diagrams, which followed elaboration discussion stable phases. Then, theoretical Monte Carlo simulations (MCSs), in framework Ising elaborated investigate By doing so, number results achieved, namely reduced critical temperature that determined ( Tc/ Jσσ) through studying total partial magnetizations susceptibilities function temperature. effects crystal field on magnetizations, for different values exchange coupling external field, explored discussed. Finally, hysteresis loop behaviors established
