Ferromagnetic properties of Fe and Ni in relation to their band structure

Abstract

Several properties of the elements Fe and Ni can be correlated with each other by means of an empirical theory, which assumes that the atomic magnetic moment does not have a constant value in transition metals, but is thought to depend in these cases on temperature, volume, and external magnetic field. The properties in question are, among others, the field-dependent volume magnetostriction, the change of magnetization and Curie point with pressure, and the deviations of the temperature dependence of the saturation magnetization from the appropriate Brillouin curves. Variations of the atomic magnetic moment are estimated by incorporating localized magnetic moments into the electron band theory of the 3d-electrons
