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).
