Oxygen Nonstoichiometry and Thermodynamic Explanation of Large Oxygen‐Deficient Ruddlesden–Popper Oxides La x Sr 3− x Fe 2 O 7−δ

The oxygen nonstoichiometry of large oxygen‐deficient Ruddlesden–Popper oxides La x Sr 3− x Fe 2 O 7−δ (LSFO7‐ x ) ( x  = 0, 0.25, 0.5) was measured by the high‐temperature gravimetry and the coulometric titration. In the composition series, the P (O 2 ) dependencies exhibited typical plateaus at δ ...
