Abstract

A sequence of experiments has been performed to measure thermal properties of liquid and solid 3He between the temperatures 1 and 25 mK at melting curve densities. A two-phase mixture of 3He sample was self-cooled by the Pomeranchuk method. A heat pulse technique was used, combined with measurements of pressure and volume, to yield separate determinations of liquid and solid properties: the specific heat of liquid 3He in the normal Fermi liquid and superfluid phases; the entropy of solid 3He above and through a nuclear magnetic transition at 1.10 mK; and an absolute thermodynamic temperature scale based on measurement of latent heat of conversion of liquid to solid.
