摘要：

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 x 10(-8) and 1.7 x 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.
