Abstract

Single crystal sof the 84-K superconductor Bi2.2Sr2Ca0.8Cu2O8+ were characterized by x-ray diffraction, dc magnetic susceptibility, electrical resistivity, and microwave absorption. The structure has [CuO2] planes separated by calcium atoms, edge-shared bismuth oxide double layers, and an incommensurate superlattice along b with a period of 4.76. The in-plane resistivity above Tc is linear in T, with RT=130 cm. Initial results on Pb substitution yielding Tc's of 107 K are reported.
