Specific Heat of Alpha-Manganese at Liquid-Helium Temperatures

Abstract

The heat capacities of two independently prepared specimens of $\alpha$-Mn have been measured between 1.75 and 4.2°K. The coefficient of the contribution linear in $T$ is found to be (30.6±1.5)×${10}^{-4\mathrm{}}$ cal/mole${\left(\mathrm{°}\mathrm{K}\right)}^2$. This value is in reasonable agreement with that determined by Booth, Hoare, and Murphy from measurements made in the liquid-hydrogen range.
