Abstract

Bi2−x Pb x Sr2Ca2Cu3O y superconducting samples with 0<x<0·3 have been synthesized and characterized using X-ray powder diffraction.T c and superconducting volume fraction have been measured using a.c. magnetic susceptibility, d.c. electrical resistivity as well as X-band microwave surface resistance in the normal state. The data indicate the growth of the highT c (2223) phase with corresponding reduction of the lowT c (2122) phase with increasingx, up to 0·25. Beyond this value ofx there is a slight deterioration of the superconducting behaviour.
