Low temperature heat capacities of constantan and manganin

Abstract

The heat capacities of Constantan and manganin have been measured from 0.15 and 0.2° K, respectively, to 4.2° K. Both alloys have large hyperfine heat capacities at temperatures of a few tenths of a degree and data are presented which can be used in making corrections to calorimetric measurements in which one of these materials is used as a heater. © 1963 The American Institute of Physics.
