Abstract

Samples of nominal composition (Bi_2-xSb_x)Sr₂CaCu₂O_y (0.1≤x≤0.3) are investigated. X-ray diffraction and electron diffraction show that the (Bi_2-xSb_x)Sr₂CaCu₂O_y system has a monoclinic phase with the lattice parameters a=21.73 A ̊, b=5.76 A ̊, c=19.32 A ̊ and β=95.0°, except for the tetragonal Bi-2212 phase. The results of energy dispersive X-ray spectroscopy reveal that Sb does not substitute for Bi in the Bi-2212 main structure, but forms the monoclinic phase of Bi₄Sr₄Ca₂SbO_y. The superconducting transition temperature, which is examined by electric resistance and AC magnet susceptibility, is constant at about 87 K. The reason why Sb cannot substitute for Bi in Bi₂O₂ layers has been discussed from the point of view of coordination.
