Ligand-hole localization in oxides with unusual valence Fe
Unusual high-valence states of iron are stabilized in a few oxides. A-site-ordered perovskite-structure oxides contain such iron cations and exhibit distinct electronic behaviors at low temperatures, e.g. charge disproportionation (4Fe(4+) → 2Fe(3+) + 2Fe(5+)) in CaCu(3)Fe(4)O(12) and intersite char...
