Abstract
Mixed ionic and electronic conductivity was obtained in Gd2Ti2O7 by do ping with Mn. This was confirmed by measuring the nonstoichiometry and the electrical conductivity as a function of oxygen partial pressure, temperature and Mn concentration. The results were combined with the defect and transport models, to derive key thermodynamic and kinetic p arameters of Gd2Ti2O7 doped with Mn.
