Abstract

Using a specially designed mixing chamber for a dilution refrigerator and a magnetometer employing a superconducting device we have compared, over the temperature range 12 to 100 m°K, the static temperature-dependent moment of a sample of pure copper (resistance ratio 31,500) in a field of 5.8 G with the 17 Hz susceptibility of powdered cerium magnesium nitrate (CMN). Using cross-calibrational information from experiments on Cu(Mn) alloys we deduce that within the accuracy of measurement the observed temperature-dependent magnetic moment of the pure copper can be ascribed to nuclear magnetism only, with a calculated Curie constant of 4.5×10−8°K. The experiments are not sufficiently precise to shed new light on the CMN temperature scale, but are not in disagreement with our earlier conclusions. A remarkable but unexplained electronic Curie-law background magnetization is observed in the empty magnetometer.
