Calculation of Fermi surface orbit integrals using a tetrahedron method. II. Dingle temperatures for 3d transition metal impurities in Cu

Abstract

For pt.I see ibid., vol.10, no.3, p.407 (1980). Calculations of Dingle temperatures for 3d transition metal impurities in Cu are presented for five extremal orbits. Also the orientation dependence of the Dingle temperatures in the planes (110) and (100) for Ni and Fe impurities is calculated. The scattering properties of the impurities are described in terms of effective scattering phaseshifts obtained from an impurity model potential of muffin-tin type. The bandstructure of the Cu host was calculated using the H-NFE-TB scheme; the numerical integration along the orbits over the Fermi surface was performed using the tetrahedron method.
