摘要：
The specific heats of Sm1+xBa2-xCu3Oy solid solution of orthorhombic and tetragonal structure were measured in the temperature range 80-300 K. The data were analyzed in the framework of the Debye model with dilatation correction. The tendency to lower the high-temperature limit of the Debye temperature, THETA(D)HT, with the oxygen deficiency was noticed. In contrast, the increase of Sm substitution causes a rise of THETA(D)HT. The temperature dependence THETA(D)(T) was calculated for each compound from the series for the whole temperature region investigated.
