LXXXIV. The specific heats of magnesium and zinc

Abstract

Abstract Specific heat measurements have been made on magnesium from 1°k to 20°k and on zinc from 4°k to 20°k. The magnesium data agree with the most recent measurements above 15°k, whilst the results on zinc confirm one set of earlier data. The shape of the curve of the Debye θ versus temperature for magnesium is found to be similar to that for beryllium. The θ value rises from a constant value of 326° above 30°K to 406° at absolute zero. The θ value for zinc rises much more sharply from a value of 195° at 20°K to 291° at absolute zero.
