Abstract

The superconducting properties of the Bi1.7Pb0.3Ca2-xYxSr2Cu3Oy system have been investigated by X-ray diffraction, SEM, DC electrical resistivity, AC susceptibility and Thermo Electric Power measurements. With increasing Y concentration the volume fraction of the high Tc (2223) phase decreased and that of the low Tc (2212) phase increased and also Tc (0)'s and Tc(onset)'s have decreased. The AC susceptibility measurements have shown the granular nature of the superconductivity. The thermoelectric power measurements have shown that the charge carrier concentration decreases with increasing Y concentration.
