- Abstract
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 system, 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 ferromagnetic system is selected as small as possible, and Monte-Carlo steps are performed 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.
