Specific heat of versus temperature. Shown are the single-crystal raw data [2], the processed data of Johnston [7] subtracting (extrapolated) polycrystalline from polycrystalline , and the processed data of the Comment [1] subtracting (extrapolated) polycrystalline from single crystalline . All data sets clearly show a kink in the specific heat of below 10 K. Also, the processed data of 1 agree well with our theoretical fit formula in the relevant temperature range, i.e., around the kink. At higher temperatures, deviations are to be expected [3, 6].Reuse & Permissions
