The impact of structural features on ion and electron transport in Y0.25Sr0.75FeO3−δ

•Structure, oxygen content, and charge transport in Y0.25Sr0.75FeO3−δ is studied.•Incommensurate modulation with ±q ~0.42 〈100〉p* is revealed by electron diffraction.•The feature originates from the large difference in the sizes of Y3+ and Sr2+ cations.•Structural distortion is found to promote oxyg...
