Investigation of Thermodynamic Properties of Magnetic Dendrimer by the Wang-Landau Algorithm
The magnetic dendrimer model is investigated by high-performance Wang-Landau algorithm of the Monte Carlo method. The Wang-Landau algorithm allows to calculate the probability density of a system and the temperature dependences of thermodynamic parameters such as free and internal energy, entropy S, the heat capacity C, magnetization m, and susceptibility χ for various linear sizes. The study has shown shown that depending on the ratios of the exchange interaction parameters J1 and J2, the ground state of the system can be ordered or frustrated, highly degenerate.
