Abstract
The static magnetization of pure Al and Tl, and of Pt containing 70 ppm Fe, has been measured over the temperature range 10–400 mK. It is shown that the temperature-dependent magnetism of pure Al and Tl can be attributed to nuclear magnetism only, with calculated Curie constants 6.9×10−8 and 1.7×10−8 K, respectively. The magnetization of Pt containing 70 ppm Fe in a magnetic field of 10 Oe was found to obey a Curie-Weiss law over the entire temperature range studied. The adequacy of Cu, Al, Tl, and Pt as magnetic thermometers in the millidegree temperature region is discussed.
