Abstract

Superconductivity is found in tetragonal La3-x Ba3+x Cu6O14+δ and La, Ba)6-x Sr x Cu6O14+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.
