✦ Synopsis

The specific heat of the superconductors YBa2Cu3Ox, Bil.6Pbo.4Sr2Ca2Cu3Oy, & Nd1.85Ce0.15CuO z was studied as a function of temperature between 300 and 750 K by means of Differential Scanning Calorimetry technique. For Y-based system, it goes from endotherm for orthorhomic structure to exotherm for tetragonal structure in the temperature range roughly between 600 and 750 K. For Bi-and Nd-based systems, The DSC (or TG) data are linearly increased (or decreased) functions of temperature between 300 and 750 K; this suggests that the oxygen is gradually desorpted.
