Description
Twinned structure with twin plane (510) and with the composition plane (001) is observed in a high-Tc Bi–Sr–Ca–Cu–O superconductor which is orthorhombic with a=0.54, b=2.7 and c=3.08 nm. Directions of “Bi-concentrated bands” in both twin individuals are perpendicular to each other. Local intergrowths of perovskite-related layers with 1.8 and 2.1 nm thickness are observed among the major layers of 1.5 nm. The material includes small amounts of crystal with c=3.6 nm, which may be responsible for the superconductivity at 105 K, as already suggested by Muromachi et al. (Jpn. J. Appl. Phys. 27 (1988) L556).
