Electrical Conductivity and Chemical Diffusion Coefficient of Strontium-Doped Lanthanum Manganites

Electrical conductivity and chemical diffusion coefficient of Sr-doped lanthanum manganites, La1−xSrxMnO3±δ(x= 0.05 − 0.20), were measured by the dc four-probe technique and relaxation type experiments where a sudden change of oxygen chemical potential was imposed on the pre-equilibrated sample and...
