    • Abstract

       

      Superconductivity is found in tetragonal La3−xBa3+xCu6O14+δ and La, Ba)6−xSrxCu6O14+δ even though they do not possess Cu-O chains or the K2NiF4 structure. Resistivity measurements confirm the occurrence of a transformation from chain-superconductivity to sheet-superconductivity in YBa2Cu3O7−δ as δ is varied in the range 0.0–0.5.
