Heat Capacity of Palladium below 4.2°K

Abstract

Heat capacity measurements below 4.2°K have been made on extremely pure palladium. The resulting values of electronic heat capacity and Debye temperature differ from previous work, it being found that $\gamma =(9.87\mathrm{}\pm 0.11)\times {10}^{-3\mathrm{}}$ joule ${\mathrm{mole}}^{-1\mathrm{}}$ ${\mathrm{deg}}^{-2\mathrm{}}$ and $\theta =299\mathrm{}\pm 12°$K. The effects of changes in the physical and chemical state of the specimen have been investigated with a view to understanding the discrepancies between the various determinations of the low-temperature atomic heat of palladium.
