Abstract

A direct method of analysis of valence electron distribution from their crystal structures, are applied to α‐Fe, ε‐Co, Ni based on the fine structure of atomic valence of type A hybridization of states of Fe, Co, Ni. Their valence electron distributions and theoretical magnetic moments of 3d are obtained. Using known spectroscopic splitting factor g and experimental total magnetic moment, the magnetic moment of the orbital morb and of the 4s electron m4s, are calculated, whose negative sign is independent of the choice of known values of g. The results agree with the neutron diffraction experimental data to the first order of approximation. The theoretical bond lengths also agree with the values directly calculated from the crystal structures. Based on the valence electron distributions and the negative sign of m4s deduced theoretically, the interpretation of the negative magnetic moment distributions as lattice electrons appears reasonable.
