Heat Capacities from 1 to 30 K of Zn, Cd, Sn, Bi, and Y

Abstract

The specific heats of the anisotropic metals zinc, cadmium, tin, bismuth, and yttrium have been measured from 1 to 30 K with an accuracy in most instances of 0.5%. Each of these materials showed a relatively rapid decrease in equivalent ${\Theta }_D$ with increasing temperature, a characteristic of anisotropic solids. The present results are in agreement with other similar quality data where overlaps exist. The results for the yttrium sample are somewhat ambiguous because of the existence of an anomaly which becomes important below 4 K and which is believed to be due to magnetic ordering of the rare-earth and transition-metal impurities in the sample. Low-temperature parameters, tabulated smoothed results, and reduced ${\Theta }_D\mathrm{}\left(T\right)\mathrm{}$ plots are given for each of these metals.
