An insulating polymorph with a composition close to Bi2Sr2CuO 6 complicates the synthesis of the single copper layer superconductor Bi2+xSr2\_yCuO6e~. We concentrate on the region where the material is single phase in air synthesis (2.18 <x<2.29, 1.44 < y< 1.7 ). The physical properties from insulat
The effect of oxygen nonstoichiometry and barium cation substitution on the structure and superconducting properties of Bi 2 Ba 2-x M x CuO 6+δ (M = Sr, Ru, Rh, Pd, In, Sb or Pb; x changed from 0 to 0.2) were studied. The cation-substituted samples annealed in oxygen flow contain a superconducting p
