We report precise measurements of the thermoelectric power (TEP) of granular superconducting Bi 1.75 Pb 0.25 Ca 2 Sr 2 Cu 3 O 10. The TEP is strictly linear at high temperature. Superconductivity fluctuations set in at about 140 K. From the temperature derivative of the excess TEP (with respect to a straight line at “high temperature”), the critical behavior is obtained in the mean field regime, and is found identical to that of the temperature derivative of the excess electrical resistivity.

Resonating Valence Bond

In this talk the Resonating Valence Bond (RVB) state of the Mott- Hubbard insulator and the high temperature superconductivity resulting from doping are described as the possible mechanisms for the insulating and high temperature superconducting properties of undoped and doped La2CuO4 and other high Tc oxides. We describe in detail two microscopic approaches to the understanding of the RVB superconductivity- one is a simple mean field theory and the other is a gauge theory.
