Specific Heat of Niobium between 0.4 and 4.2°K

Abstract

Below 3.3°K, the normal-state specific heat of niobium, measured in a magnetic field of 17 kG, can be represented by $C_n=7.79T+0.094\mathrm{}{T}^3$ mJ/mole deg. This corresponds to a value of the Debye parameter at 0°K, ⊖(0), of 275°K. The specific heat in the superconducting state does not appear to be anomalous, as has been reported.
