Electronic density of states in pseudo-binary compounds

A new method to calculate the electronic density of states in pseudo-binary intermetallic compounds of (A 1-x B x ) m C n type is developed by combining the coherent potential approximation and the recursion method. Numerical examples are given for the density of states of the tight-binding s-band model with a simple atomic structure. An application to the tight-binding d-band model for Y(Fe-Co) 2 and Y(Mn-Co) 2 compounds with the cubic Laves structure is also given.
