Abstract
The electrical resistance of CuGeMn alloys was measured as a function of temperature. It shows maxima at temperatures between 1.5 K and 9.1 K. Since the temperature coefficient at the maxima is zero and since the resistivity is high, these alloys are very suitable for the construction of cryo-resistors which are operated in liquid helium and can be used to improve quantum Hall measurement systems.<>
