摘要：

Heat capacity results for single-phase, polycrystalline samples of high- Tc ceramic super-onductors YBa2Cu3O6.98, EuBa2Cu2O6.80 and HoBa2Cu 3O6.90 are reported. The samples were obtained from the sintered products of well-reacted M2O3 BaO2 and CuO powders. The calorimetric measurements were performed in a continuous-heating, computer-controlled calorimeter in the temperature range 77-300 K. The heat capacity behaviour of YBa2Cu 3O6.98 in different low magnetic fields is also reported. © 1990.
