ELECTRONIC-PROPERTIES AND FERMI-SURFACE OF NI3PT

We present calculations of the electronic properties of ordered Ni3Pt using the linear-muffin-tin-orbital method. Calculations are performed for the paramagnetic and ferromagnetic phases. Our total-energy calcu lations show that the ferromagnetic state has a lower energy. Hence th e ferromagnetic phase is studied in detail. The calculations are done at a theoretical equilibrium lattice constant. The results for density of states, bulk modulus and magnetic moment at the equilibrium lattic e constant are reported here. Also a brief discussion of the Fermi sur face of ferromagnetic Ni3Pt is presented.
