STUDY OF TRANSITION-METAL ALUMINIDE ALLOYS

We have studied the densities of states of the series of alloys FeAl, CoAl, and NiAl, each in the disordered state, using the augmented-spac e recursion technique coupled with the tight-binding muffin-tin orbita ls method. We have estimated the local moments in these alloys using t he spin-polarized version of the tight-binding linearized muffin-tin o rbitals method. We have also obtained the effective pair interactions for these alloys.
