This paper discusses a simple calculation for the diffusion thermopower of a transition metal ferromagnet. The main result of this calculation is that unlike in the case of a free-electron model, the diffusion thermopower S and its derivative with respect to temperature dS/dT have opposite signs. The results of this calculation agree qualitatively with experimental results in the high temperature region, where the diffusion thermopower is dominant.
