Shielding studies of electrochemically oxidised La2CuO4

Structural Characterization of Electrochemically Oxidized La2CuO4+δParticles Prepared by a Sol–Gel Method

“…It itself is an antiferromagnetic insulator, but it can be converted to a superconductor at +40 K, either by partial M(II) substitution in the La(III) sites (6,7) or by insertion of additional oxygen into interstitial positions. The latter can be achieved by annealing the base material at high temperatures (+500°C) in high oxygen partial pressure (8,9) or by a simple anodic oxidation of the undoped compound in an aqueous KOH solution at room temperature (10)(11)(12)(13).…”
