Normal state transport properties of (Bi0.8Pb0.2-yVy)(2)Sr2Ca2Cu3O10+deltasuperconducting pellets

The electrical resistivity and thermoelectric power of (Bi0.8Pb0.2-yVy)(2)S r2Ca2Cu3O10+delta pellets with 0 less than or equal to y less than or equal to 0.05 is reported between T-c0 and 300 K. Thermoelectric power values of all samples were found to be positive and increase almost linearly with de crease of temperature down to similar to 120 K, before falling to zero at T -c0. With increasing vanadium content in (Bi,Pb)-2223 compounds, the magnit ude of both the electrical resistivity and thermoelectric power increases. General features, however, remain the same. The results have been discussed on the framework of a "three-state model". Our analysis shows an excellent agreement between the measured electrical resistivity and thermoelectric p ower data and those calculated using the three-state model.
