On the basis of the band structure described in Part I an interpolation scheme is discussed which allows to make a transformation of the band structures of the A2‐, B2‐, and DO 3 ‐type lattices into another ones. For disordered alloys the CPA theory in split‐band approximation reveals a d‐band narrowing without changing the shape. For partially ordered alloys a combined model is proposed which gives a dependence of the magnetic moments on the proportion of pair probabilities in first and second neighbourhoods, in contradiction to former assumptions, which presume a dependence on the first sphere alone.
