Abstract

Copper oxide containing superconductors, such as the La2-xSrxCuO4 and REBa2Cu3O9-x (RE is Y and most other rare earths), have been shown to have high transitions. As of now the mechanism responsible for these high transition temperatures is not known and there is no generally accepted theory explaining why these copper oxides are unique. The transition temperature is directly related to the copper (III) concentration.
