Abstract

Superconducting Bi-Sr-Ca-Cu-O ceramics with intergrowth defects larger than 1.8 nm in half of the c-axis length were synthesized at a nominal composition of Bi₂Sr₂Ca₄Cu_6.5O_y. Electrical resistance and a.c. susceptibility for the ceramics were measured. No indication of a T _c higher than 110 K was obtained.
