XCIII. The heat capacities of chromium and nickel

Abstract

Abstract Heat capacity measurements have been made below 4·2°K on extremely pure specimens of chromium and nickel. In both cases the measurements give γ values lower than those obtained by former observers. The values of Debye temperature also differ significantly from those of previous work, it being found that θ=630°K for chromium and 0=440°K for nickel in contrast to the older figures of 418°K and 413°K respectively. These new results help to resolve the apparently anomalous nature of the θ versus T curves for the two metals. The influence of the magnetic heat capacity on the results for nickel is also discussed.
