Abstract:
The thermodynamic properties of the models of magnetic dendrimers were studied by the Monte Carlo method. The system state density is calculated; the ground state structures are determined. The temperature dependences of magnetization m, entropy S, internal energy E, and heat capacity C are calculated. It is shown that in the investigated model of dendrimer, the effect of the surface sites on the general behavior of the system does not become weaker with growing sizes of the system.
