The concentration dependence of the residual resistivity of Ni&sngbnd;Pd alloys might be expected to obey a simple Nordheim law since the number of holes in thedband and the number of electrons in thesband are approximately independent of composition. Measurements have indicated, however, that the maximum resistivity occurs at 70 atomic percent Pd instead of 50%. This behavior can be explained by the spin dependence of electron scattering processes associated with the fact that the alloys with greater than 3% Ni are ferromagnetic. Quantitative fit of the data is possible if it is assumed that the density of states at the Fermi energy in thedband is approximately proportional to the number of holes, rather than to the cube root of this number. Data on the resistivity and paramagnetic susceptibility of Ag&sngbnd;Pd alloys support this hypothesis. The relative strength ofs‐dscattering tos‐sscattering must be assumed to be about 5:1.
