“Average Spin” Approximation in the Heisenberg Model

Abstract:

The “average spin” method was developed in terms of Heisenberg model. The average magnetic moment’s depending average of the temperature, the number of the nearest neighbors and spin of the atom has been calculated. It’s shown that the Curie temperature decreases with the spin of the atom.
