Abstract
Measurements of the electrical and thermal resistivities and absolute thermoelectric power of polycrystalline pure nickel and a number of dilute nickel-copper alloys have been made in the temperature range 2°K to 120°K. Although the overall pattern of the results is similar in character to that found in a dilute alloy which does not contain a transition metal, there are a number of quite distinct anomalies. These include marked deviations from Matthiessen's rule, a decrease in the values of the Lorenz number of the alloys to a value less than the classical value L 0 at temperatures below 10°K and pronounced maxima in the thermoelectric power versus temperature curves of the two most dilute alloys at about 45°K.Keywords
