Powder Metallurgy and Metal Ceramics Aims and scope

Abstract

We have studied the heat capacity of Gd5Ge3, GdGe, GdGe1.5 for the first time by the adiabatic method at temperatures of 55 K to 300 K. Using low-temperature measurements, we have calculated the values of the enthalpy, the entropy, and the reduced Gibbs energy of the germanides under standard conditions.
