Movilidad de oxígeno en conductores iónicos A<sub>2</sub>Ti<sub>2-y</sub>Zr<sub>y</sub>O<sub>7</sub> (A: Y, Gd)

We report a study of ionic conductivity in the series Y2Ti2-yZryO7 and Gd2Ti2-yZryO7 (0≤y≤2) obtained by mechanochemical synthesis. We present a study of oxygen ion dynamics in these materials by Impedance Spectroscopy. The change in dc conductivity and activation energy with Zr content is interpret...
