ELECTRONIC STRUCTURE AND GROUND STATE PROPERTIES OF NON-MAGNETIC NiPt SYSTEMS.

We have studied the electronic properties like density of states and band structures and also the ground state properties like formation energy, cohesive energy, bulk modulus and structural energy of NiPt system using the linearized muffin-tin orbital method introduced by Andersen.[sup 1,2] In an earlier communication we had argued that both charge neutrality and scalar relativistic corrections are very important for the high concentration of Pt alloys. The calculations here, were, therefore, carried out with charge neutrality as well as with and without scalar relativistic correction for comparison. [ABSTRACT FROM AUTHOR]
