Abstract
For pt.I see abstr. A.64186 of 1974. The 'noninteracting' and 'interacting' dynamical susceptibilities of ferromagnetic substitution disordered binary alloys treated within the CPA-HF approximation are derived, in the single and multi orbital cases. The spin wave stiffness constant D and the magnetic moments on the alloy components, are computed as a function of the concentrations, for a model simple cubic tight binding s band and for a multiple orbital Ni-Fe alloy, using a realistic band shape for Ni. The results are in good agreement with experiment.Keywords
