Specific Heat of a Body-Centered Cubic Cr-Fe Alloy between 30° and 110°K

The specific heat of a body-centered cubic alloy, ${\mathrm{Cr}}_{80.6}$ ${\mathrm{Fe}}_{19.4}$, was determined between 30° and 110°K. The electronic specific heat coefficient $\gamma$ and the Debye characteristic temperature were evaluated between 40° and 60°K to be (46±5)×${10}^{-4\mathrm{}}$ cal ${\mathrm{mole}}^{-1\mathrm{}}$ ${\mathrm{deg}}^{-2\mathrm{}}$ and 472±14°K, respectively. The origin of a sharp peak occurring at 37±2°K is discussed.
