Abstract
The physical properties of perovskite iron oxides are closely related to the network of FeO 6 octahedra. The charge disproportionation (2Fe 4+→Fe 3++Fe 5+), not observed in SrFeO 3, occurs in the oxides being cut the network of Fe 4+O 6 octahedra, for example, by introduction of Fe 3+ by substitution La for Sr and change in the dimension by insertion of SrO layer. When Co is substituted 40% of Fe in Sr 3Fe 2O 7, the magnetic order changes to ferromagnetic from antiferromagnetic and charge disproportionation is suppressed.
