The Influence of Sr-Dopant on Ionic Conducting Properties of La_(1-x)Sr_xMnO_(3-δ)

The structure of La 1- x Sr x MnO 3- δ and its ionic conducting mechanism are investigated at high temperature.At x=0.5,the ionic conductivity is the highest in oxygen deficient region.The oxygen ionic vacancy is the pathway of the oxygen ion,the pathway can link up for x=0.5.
