Low-temperature heat capacity of metals

The low-temperature heat capacities of transition metals and alloys were reviewed by Heiniger, Bucher, and Muller¹ in 1966, with particular emphasis on the dependence of the electronic heat capacity on the number of conduction electrons. Nuclear contributions to the heat capacity of metals and alloys have been reviewed recently by Lounasmaa.² The most recent general review of the low-temperature heat capacities of metals, however, was that by Keesom and Pearlman³ in 1956. Since that time there have been important advances in experimental techniques and also in theory related to certain of the heat capacity contributions.
