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 Can−1 Cun O2n+3−δ , are reported. The detailed atomic level microstructure of the compounds have been determined and computer simulated with structural models. Tc 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 Tc ’s for the same value of n.Keywords
