ELECTRONIC SPECIFIC HEAT AND SATURATION MAGNETIZATION OF CR-FE AND FE-CO ALLOYS

Abstract

The collective model of ferromagnetism is applied to various models for the upper third of the 3d band profile of bcc alloys of transition metals. In the first band profile, a rectangular subband with rounded lower and upper edges is considered, assuming an intra-atomic exchange integral just large enough to produce ferromagnetism. The low-temperature specific heat coefficient has a sharp peak at the electron concentration where ferromagnetism starts (almost empty sub-band), and a deep minimum at the concentration with largest saturation magnetization (half-filled sub-band).
