Electronic density of states in pseudobinary compounds. II. The effect of off-diagonal randomness

Abstract

For pt.I see ibid., vol.17, p.2067 (1987). A simple method to calculate the electronic density of states is developed by making use of the coherent potential approximation and the recursion method by taking account of the randomness of atomic potentials and transfer integrals. This is a generalisation of the method developed previously. An application to calculate the density of states is given for Y(Mn-Co)2 Laves phase pseudobinary compounds by using the tight-binding d-band model.
