ELECTRONIC-STRUCTURE OF RANDOM BINARY-ALLOYS

We present here an application of the augmented-space recursion techni que for binary disordered alloys. The method allows us to incorporate effects like clustering, short-ranged order and off-diagonal disorder arising out of size mismatch and consequent lattice distortions. We ba se our calculations on the TB-LMTO Hamiltonian of Andersen and coworke rs. We study three alloy systems: AgPd, CuZn and FeTi, and compare our results with earlier work.
