  We introduce the Hamiltonian to describe narrow band electrons. The physics
of driving forces towards ferromagnetism is re-examined. Using different
approximations it has been shown that the magnetic moments created by
inter-site interaction and inter-site kinetic correlation decrease quickly with
temperature. As a result of these interactions and the realistic density of
states (DOS) the Curie temperatures calculated after fitting magnetic moments
to their low temperature values are realistic. In the past the Curie
temperatures calculated using only the on-site interaction were much higher
than the experimental temperatures.
