A self‐consistent calculation of magnetic properties beyond the homogeneous molecular field approximation is given. It was found that the Curie temperature, due to fluctuations of the exchange interaction only, increases. It is also shown that the magnetic properties inherently depend on higher spatial correlations of spins then pair‐pair ones.
