THERMOELECTRIC EFFECT IN THE HOLLOW SUPERCONDUCTING CYLINDER OF PB AND PB-IN ALLOY

The technique for measuring of the thermoelectric effect in supercondu ctors near the critical temperature T-C has been elaborated. The measu red magnetic flux was induced by temperature gradient (Delta T similar to 1 K) between joints. The experimental study of the thermoelectric effect has been carried out in the hollow bimetallic superconducting c ylinder consisting of the Pb and Pb-In alloy. The observed temperature dependence of the thermoexcited magnetic flux has been well approxima ted by the logarithmical function. The magnitude order of the thermopo wer estimated from the experimental data coincides with the known low temperature thermopowers of metals.
