The specific heat of samarium and holmium in the range 2-32 K

Abstract

Measurements of the specific heat in the temperature range 2-32 K have been made on a high-purity single crystal of holmium and two polycrystalline samples of samarium. Holmium shows a discontinuous transition at 19.46 K with an entropy of 0.14+or-0.02 J mol-1 K-1 and a latent heat of 2.7+or-0.3 J mol-1. There is a small peak at 17.3 K. Samarium has a large peak at 13.7 K, a smaller peak at 20.4 K and a very small anomaly at 9.6 K. The size and shape of the peaks depends upon the purity of the sample. Show more
