摘要
The heat capacity of the high-Tc superconductor YBaSrCu3O7 ‡ was measured by adiabatic calorimetry between 7 and 300 K. The temperature dependence of heat capacity was found to exhibit anomalous behavior at 94 and 255 K. The Debye characteristic temperature was determined to be θD = 369 K at low temperatures. The heat capacity data were used to assess the thermodynamic properties of YBaSrCu3O7-δ in the range 5–300 K.
