Abstract
Resistivity measurements have been made on a dilute alloy of 0.07 at.% Co in Pt in the temperature range of 1.0 to 20°K. We find that the net resistivity, , is linearly proportional to in this temperature range, in accordance with Kondo's exchange scattering theory when the effect of ordinary scattering is taken into account. We also find that the net resistivity is linearly proportional to , where is the effective moment associated with the Co impurity and surrounding Pt electrons, which decreases at lower temperatures, as deduced from nuclear-magnetic-resonance linewidth measurements in the same system. This kind of behavior is predicted by Knapp's two-band model.
