Effect of deformation on the temperature dependence of the resistivity of palladium-molybdenum and palladium-tungsten alloys

We have measured the temperature dependence of the resistivity of alloys of the palladium-molybdenum and palladium-tungsten systems between 10 and 300 K. These alloys exhibit a decrease in electrical resistivity after deformation, contrary to the expected increase due to increased scattering from dislocations. It is shown that these changes are associated with significant alterations in electronic structure brought about by changes in atomic configuration in the lattice.
