Oxygen chemical diffusion in strontium doped lanthanum manganites

The chemical diffusion coefficient of oxygen in (La 0.79Sr 0.20)MnO 3−δ and (La 0.50Sr 0.50)MnO 3−δ was measured in a solid state electrochemical cell using the potentiostatic step method. In the temperature range between 700°C and 860°C, the chemical diffusion coefficient of oxygen in (La 0.79Sr 0....
