Высокотемпературный ионный и электронный транспорт в перовскитоподобных оксидах La1–xSrxFeO3–δ

Abstract

Synthesis of La1–xSrxFeO3– (x = 0.45, 0.5, 0.6, 0.65) was carried out via a one-pot autocombustion method. Electrical conductivity was measured at 750950C in the oxygen partial pressure range 10–19 – 0.5 atm. The partial contributions to conductivity from oxygen ions and electrons were found to attain maximal values at x = 0.5.
