Using a volumetric method, the relationship among the oxygen desorption and absorption equilibrium pressure P, excess oxygen , and temperature T (P+ +T ) has been investigated for polycrystalline LaMnO 3؉ . To interpret the measured P+ +T relation, we have proposed a defect model in which La and Mn
