Combined interpolation scheme for calculating the electron energy spectra of alloys of 3d transition metals

A model Hamiltonian is used as the basis of a combined interpolation scheme for calculating the spectra of ordered alloys of 3d transition elements with the CsCl and Cu₃Au structures. The parameters of the model Hamiltonian are found for the alloys FeCo and Co₃Ti and the histograms of the density of states are calculated at 165 points in 1/48-th part of the Brillouin zone. The results are evidence of the effectiveness of the use of such a combined interpolation scheme in calculating the integrated characteristics of the electron structure of alloys with large numbers of atoms in a unit cell.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 6, pp. 65–70, June, 1980.
