Abstract
By interfacing a solid electrolyte with an oxide superconductor it has been shown that it is possible to introduce oxygen into the structure electrochemically. By measuring the Nernst potential across the electrolyte, the oxygen activity in the oxide superconductor has been determined. When a mixture of cuprous oxide and copper was used as the source of oxygen, insertion was performed, totally in the solid state. From the decay curves, diffusion coefficients were estimated.Keywords
