Large area (up to 2 cm2) thin (10–100 μm) single crystals of Bi2+xSr2−xCuO6+y (“2201”) were grown using a self-flux technique. These crystals grow with the c-axis perpendicular to their platelet-like surface, with a cation composition, as de

The magnetic behavior of single crystals and powders of ${\mathrm{BiPbSr}}_{2}$${\mathrm{MnO}}_{6}$ and ${\mathrm{BiPbCa}}_{2}$${\mathrm{MnO}}_{6}$ has been measured between 300 and 4 K. These analogues of the high-temperature superconducting bismuth

The substitution of bismuth by lead was performed in the compound Bi2−xPbxSr2(Sm0.85Ce0.15)2Cu2O10+y. Its influence on the superconducting properties as well as on the structure was studied by X-ray diffraction, transmission electron microscopy (TE

The effects of a substitution for Cu by other 3d metals (Ni, Co, and Zn) on ${\mathit{T}}_{\mathit{c}}$ in the Nd-Ce-Cu-O system was studied and compared with effects of the same ions on ${\mathit{T}}_{\mathit{c}}$ in the La-Sr-Cu-O system. We found
Ba site vs. Pb/Bi site chemical substitution in the (Ba, A)(Pb, Bi, Tl)O3 (A = K, Sr) superconductor

Chemical subsitutions were carried out in both the Ba site and the Pb/Bi (so-called active site) in the BaPb0.73Bi0.27O3 and Ba0.6K0.4BiO3 superconductors. We found that slight deviation in Ba stoichiometry (by partial substitution of Sr for Ba or va
