Increasing Temperature

The results of specific heat measurements on ordered In −51.67 at.% Mg are presented. A superconducting transition was seen at about 0.95 K. In the normal state, the lattice specific heat varies in the usual way with temperature, i.e., the Debye temperature initially decreases with increasing temperature. This behavior was also seen in ordered equiatomic CuPt but in ordered equiatomic CuAu I the Debye temperature first goes through a maximum before decreasing to the usual minimum. The structure of all three alloys consists of alternating layers of different mass and it was initially supposed that the CuAu I result was a two-dimensional effect. However, the more recent and normal results on InMg and CuPt make this improbable and it appears that the CuAu I result is related to the behavior of pure gold which is itself anomalous.

Thermal Expansion Study

Thermal expansion measurements have been performed on a uvarovite rich garnet sample for the first time and compared with the expansion data on grossular and pyrope-rich garnets reported in the literature. A semiclassical model has been used to analyze the data and to obtain various thermodynamic parameters. Using these parameters, the lattice specific heat and the corresponding entropy have also been calculated.

Dynamical Model

The vibrational spectrum and specific heat of tantalum are calculated on the basis of the lattice dynamical model of Sharma and Joshi. The calculated specific heat and the corresponding equivalent Debye temperature show fair agreement with the experimental data of Clusius and Losa.

Practical Temperature Scale

Specific-heat measurements on silver and gold in the 15–320 K range are reported and compared with earlier measurements on these metals. The present results together with recent measurements on copper (D. L. Martin, Rev. Sci. Instrum. 58, 639 (1987)) are analyzed in terms of the Debye temperature. The results suggest a negative anharmonic contribution to specific heat for silver and gold. Structure in the results for all three metals below 60 K is consistent with known imperfections in the International Practical Temperature Scale of 1968.
