Abstract
Based on the augmented space formalism introduced by one of the authors and the recursion method of Haydock et al. (1972), they have formulated a cluster coherent potential density of states for disordered CuNi alloys for various concentrations of Ni in Cu. Clustering and off-diagonal disorder effects have been incorporated. As expected in earlier model calculations, structure is obtained in the impurity band at low Ni concentrations and these have been identified.Keywords
