Solid State Physics – Superconductivity

Determine the transition temperature of a superonductor.

Determine the transition temperature of the high-temperature superconductor YBa2Cu3O7‐x. For this purpose, the substance is cooled to below its critical temperature of Tc = 92 K using liquid nitrogen. In a four-point measurement setup, the voltage drop across the sample is measured as a function of the sample temperature using the computer-assisted measured value recording system CASSY.
