Abstract We have determined the temperature (T min) at which the resistance minimum occurs for a large number of dilute copper alloys containing Fe, Ga, In, Si, Ge, Sn, Pb and Bi as solutes. Data on the absolute thermoelectric power and size of the resistance minimum of these alloys have previously been published. For alloys of Fe, Bi and Pb, we find that (T min) n ∝ rC where n ∼ 5 and rC is the normal residual resistivity increase due to the added solute. The variation of T min with solute concentration is much smaller for Ga, In, Ge and Sn as solutes than for Fe, Bi and Pb.
