Abstract
The TSFZ method has been used to grow crystals of the Bi-oxide superco nductor of the Bi-n = 1 structure. The investigated compositions are B i2Sr2CuO6+z, Bi2.3Sr1.7CuO6+z, and Bi2+xSr1.6-LayCuO6+z (x+y = 0.4). E xcept for the stoichiometric composition, the TSFZ experiments yield p late-like crystals of the superconducting R-phase. Superconductivity w as only present in La substituted crystals and the Tc could be changed by annealing procedures. A maximum T(c) = 29 K is found for Bi2.0Sr1. 6La0.4CuO6+z.
