RESEARCH ON THE CURIE TEMPERATURE OF FERROMAGNETIC SYSTEM BY MONTE-CARLO ALGORITHM

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 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.
