Abstract
In this work, we have measured the dynamic process of thermal expansion (DPTE) of some Bi-based high-Tc superconductor samples in the temperature range 80∼130K and found that the dynamic thermal expansion of Bi-based superconductor samples (Bi2Sr2Ca2Cu3Oy (Tc=105K) and Bi1.8Pb0.4Sr2Ca2Cu 3.15Ge0.05Oy, (Tc=102K)) change suddenly across Tc. The mechanism of this phenomenon is left to be studied.
