Abstract:

The electrical resistivity of several dilute RuFe and RuCr alloys has been measured between 1.45 and 300K. The incremental resistivity for the RuCr alloys is temperature independent at low temperatures, although above about 60K deviations from Matthiessens rule occur, and these are fitted on the basis of a two current models. For the RuFe system the incremental resistivity is found to be temperature dependent, increasing as T squared below about 170K, but more slowly at higher temperatures. The origin of this temperature dependence is attributed to conduction electron scattering from localized spin fluctuations confirmatory evidence for this assignment comes from the analysis of existing measurements on the depression of the superconducting transition temperature of Ru by Fe impurities.
