Abstract

The synthesis procedure and superconducting properties of the first two members of the new series of superconductors of a general formula: (Tl, Pb) ₁ Sr₂ Ca_n-1 Cu_n O _2n+3-δ, are reported. The detailed atomic level microstructure of the compounds have been determined and computer simulated with structural models. T_c increases with n, the number of Cu-O₂ layers per unit cell, as in the single Tl-layer Tl-Ba-Ca-Cu-O compounds, but the new materials have higher T_c 's for the same value of n.
