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