AB - The Monte-Carlo algorithm is an effective method to study the Curie  temperature of a ferromagnetic system related to its exchange constant,  magnetic moment, and co-ordination number. Curie temperatures of the three  types of ferromagnetic systems are calculated, e.g., the hexagonal crystal  system, the tetragonal sys-tem, and the orthorhombic system. In order to  make the calculated magnetic moment-temperature curve fit a steep slope,  the size of the supercell of the ferro-magnetic system is selected as small  as possible, and Monte-Carlo steps are per-formed 5000000 times at each  temperature. The calculation reveals a significant result: the Curie  temperature scales with the exchange constant and the square of the magnetic  moment.
