✦ Synopsis

of noble metals and transition metals, measurements of the electrical resistance and magneto-resistance of dilute alloys of gold and silver with elements of the second series of transition metals are reported.

Wires o1 Au--Rh (0.05, 0.1, 0.4 and 0.8 at. % Rh) and Au--Pd (0.05, 0.1, 0.4 and 0.8 at.% Pd) show a minimum only in the resistance temperature curve. No maximum is found. At low temperatures there are deviations from the K o h 1 e r diagram. For some wires of Ag--Pd (0.03, 0.06 and 0.34 at.% Pd) the resistance has a minimum at temperatures of liquid helium, for other wires (0.2 and 1.43 at. %) the resistance is independent of temperature in this temperature region.

Also measurements on thin, unannealed and annealed strips of Ag--Pd (0.18, 1.0, 3.7, 5.2 and 12.5 at.% Pd) and on strips of Au--Mo are reported. In liquid helium the resistance of the unannealed Ag--Pd strips does not depend on temperature. The resistance of Au--Mo strips shows a rather deep minimum.
