THERMAL EXPANSION COEFFICIENT OF SINGLE PHASE SUPERCONDUCTOR YBa2Cu3O7-δ
-
Abstract
The thermal expansion coefficient of single phase superconductor YBa2Cu3O7-δ was measured by the method of differential parallel-plate capacitance. An obvious decrease of volume near 205K and a small jump of the thermal expansion coefficient at Tc were observed. The pressure effect was also estimated.
