摘要：

Measurements of the specific heat from 0.4 to 7 K have been made on two polycrystalline specimens of samarium of different purity. There are differences in the specific heat of the two specimens between 2 and 7 K which are attributed to differing magnetic contributions. Below 2 K, both specimens shaw a small specific heat anomaly that is most likely due to samarium oxide. For samarium, a value for the electronic specific heat of 9 +/- 2 mJ mol-1 K-2 is obtained. Magnetization measurements on the two specimens between 2 and 40 K show a large peak at 13.7 K. A smaller peak in the magnetization, corresponding to that in the specific heat, is observed at 20.4 K in the purer specimen.
