抄録

The superconducting properties of the Bi_1.7Pb_0.3Ca_2-xY_xSr₂Cu₃O_y 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 T_c (2223) phase decreased and that of the low T_c (2212) phase increased and also T_c (0)'s and T_c(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.
