Abstract

The specific heat of superconducting oxide compound, YBa2Cu3O7 −x , is studied using a quasi-adiabatic calorimeter from 4.2 to 60 K. The analysis of the specific heat data below 15 K gives a value of 17 mJ/mole K2 for the electronic heat capacity coefficient. The value ofθ D(0) is determined to be 397±8 K. The variation ofθ D with temperature was calculated in the temperature range 4.2 to 60 K.
