Abstract
The low temperature specific heat of Bi1.8Pb0.3Sr1.9CuOy has been meas ured in the temperature range from 1.5 to 8K to investigate whether it exhibits features of a d-wave superconductivity. In superconducting s ample, a specific heat anomaly was observed at T-c, while no anomaly w as observed in non-superconducting sample. The value of the specific h eat anomaly Delta C/gamma T-c was quite small compared with the BCS va lue. This is consistent with the theory of d-wave superconductors by S un and Maki.
