0.7 disordered alloys have been reported for the first time by using the pseudo-alloy-atom model. A local pseudopotential consisting of a Coulombic term outside the core and varying cancellation of interaction within the core is proposed to describe the electron–ion interaction in each of these systems. The influence of various local-field correction functions on the aforesaid properties is 64–93%. The distortion of the Fermi surface (FS) along major symmetry directions obeys the metallic behavior.
