In this work we present a model for the determination of the interactionenergy for triplet and singlet states in atoms with incomplete filled shells.Our model includes the modification of the Coulomb's law by the interactionbetween the magnetic moments of the electrons and a Heisenberg term. We findthat the energy of the triplet state is lower than the energy of the singletstate. We calculate the interaction energy between the electrons from theadjacent atoms in fcc and bcc lattices and we find that the minimum interactionenergy is attained for the triplet state. The result is presented for theinteraction between the electrons of the first coordination group. Theinteraction energy which aligns the spins is used to evaluate the Curietemperature in a mean field model. Compared to previous models, our simplemodel fits the experimental data.
