| 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.
