The Oxygen Defect Chemistry of La2−xSrxCuO4−x/2+δ
Published online by Cambridge University Press: 26 February 2011
Abstract
The equilibrium oxygen stoichiometry of La2−xSrxCuO4±y (x=O, 0.2, 0.4, and 1.0) has been determined by TGA at temperatures between 800 and 1050°C and oxygen partial pressures between 1 and 10−4 atmospheres. The changes in oxygen content with temperature, oxygen partial pressure, and strontium concentration are evaluated in terms of a defect model.
