Abstract
The contribution of optical phonon scattering to the electrical resistivity of Pd1-yNiyDx alloys is determined. This contribution decreases with increasing Ni concentration and is accompanied by a depression of the superconducting transition temperature Tc. A quantitative analysis of our data indicates that the depression of Tc cannot be entirely accounted for by variation of the contribution of the optical phonons to the electron-phonon coupling. Other possible mechanisms are discussedKeywords
