The authors discuss the metal-nonmetal transition in ferromagnetic as well as in antiferromagnetic systems having one electron per atom and described by the Hamiltonian which consists of one particle energies of electrons, intra-atomic Coulomb, and interatomic Coulomb and exchange interactions between electrons. It is found that the anomalous correlation functions corresponding to spin flip processes in the Hartree-Fock approximation give rise to the metal- nonmetal transition. The nature of phase transition in ferromagnetic and antiferromagnetic systems is compared and discussed.
