Thermodynamic Phase

Curie temperature is an important parameter in the second-order thermodynamic phase transition of a magnetic system. However, the classical Heisenberg?s mean field theory tends to overestimate heavily the temperature. In order to solve this problem, firstly, the structure of ferromagnetic and spin-glassy materials in a magnetic system is established by the Ising model. Secondly, the respective energy of ferromagnetic and spin glass states is calculated by Monte Carlo method. Finally, Curie temperature is predicted through the obtained energy, which agrees well with experimental data. A new strategy to estimate accurately Curie temperature is presented.
