Study of lattice parameters and thermal expansion coefficients on Bi1.7Pb0.3Sr2Ca2Cu3O10

Abstract

The lattice parameters and thermal expansion coefficients for Bi1.7Pb0.3Sr2Ca2Cu3O10 are obtained by the XRD method in the 92 to 285 K range. These data exhibit anomalies caused by phase‐like transitions in the temperature ranges of 135 to 151 K and 200 to 220 K, respectively. In the former range, the anomaly may be related to the superconducting transition.
