Description
Modulation-free BiPbSrLCuO6 (L=La, Pr, Nd) and BiPbSr2YCu2O8, which are isotypic with the n=1 and 2 members of the Bi2Sr2Can-1CunO2n+4 family, have been prepared and characterized. These parent compounds are nonsuperconducting, but when doped with holes by substitution chemistry give modulation-free superconducting cuprates of the general formulas BiPbSr1+xL1-xCuO6 and BiPbSr2Y1-xCaxCu2O8, exhibiting maximum Tc's of 24 and 85 K, respectively. Significantly, the hole concentration at the maximum Tc is 0.12 in the cuprate family with a single Cu-O layer and 0.22 in that with two Cu-O layers
