摘要：

The electrochemical oxidation of La2CuO4 in alkaline solution (1N KOH) has been used for preparing the superconducting phase La2CuO4+delta (delta congruent-to 0.07). Crystallographic data show an enhanced orthorhombic distortion and an increase of the unit cell volume. The transport properties reveal a sharp transition from a metallic behaviour to a superconducting state below 44 K which is corroborated by the noteworthy magnetic properties.
