TL;DR: In this paper, the perovskite-related phase SrFeO3−δ through a low temperature reaction with poly(vinylidene fluoride) was reported, and X-ray powder diffraction showed that fluorination leads to an expansion in the unit cell which is consistent with partial replacement of oxygen by fluorine and consequent reduction in the oxidation state of iron.

TL;DR: In this paper, a model related to the pattern of substitution by fluorine on the octahedral arrangement of oxygen sites around iron is proposed in which SrFeO2F undergoes a magnetic transition at about 300 K from a low temperature state with random spin directions to an antiferromagnetic state.

TL;DR: In this article, it was shown that BaFeO3−x exhibits magnetic ordering at room temperature due to interactions between the Fe3+ ions, with an ordering temperature of 645 (± 5) K.

TL;DR: In this article, the perovskite-related phases La 1− x Sr x Fe 1− y Co y O 3− δ were fluorinated with polyvinylidene fluoride.

TL;DR: In this paper, a structural model based on perovskite-related K 2 NiF 4 -type structure of this oxide was proposed in which there is direct replacement of oxygen in octahedral SnO 6 units by fluorine, as well as the presence of F at interstitial sites between BaO rock salt layers.
