摘要：
Specific-heat measurement is performed for Ca-substituted samples for Sr in Bi2.1Sr1.9-yCayCuO6+delta. Specific heat anomaly associated with the superconducting transition is observed for the samples for y = 0.8, 0.95 and 1.0. The anomalies are consistent with the behavior of the magnetic measurement and suggest the bulk effect of the 80 K-class superconductivity. (C) 2009 Published by Elsevier B.V.
