A Sr analogue of Ca0.5Bi0.5FeO3, Sr0.5Bi0.5FeO3, containing unusually high valence Fe3.5+ ions was synthesized by using a high-pressure technique. It relieves the electronic instability due to the unusually high valence of Fe3.5+ by a single charge d

A perovskite-structure oxide containing unusually high-valence Fe3.5+ was obtained by high-pressure synthesis. Instability of the Fe3.5+ in Ca0.5Bi0.5FeO3 is relieved first by charge disproportionation at 250 K and then by intermetallic charge transf

La1/3Ca2/3FeO3 with unusually-high-valence Fe3.67+ was synthesized at a high pressure and high temperature. The compound crystallizes in a √2a×2a×√2a perovskite cell in which the La and Ca ions at the A site are disordered. At 217 K the Fe3.67+

Synthesis, characterization, and thermal modification of the new layered perovskite FeLa2Ti3O10 have been studied. FeLa2Ti3O10 was prepared by ion exchange of the triple-layered Ruddlesden–Popper phase Li2La2Ti3O10 with FeCl2 at 350 °C under stati

Novel cubic perovskites SrFe(1-x)Ni(x)O3 (0≤x≤0.5) with unusual high-valence iron(IV) and nickel(IV) ions were obtained by high-pressure and high-temperature synthesis. Substantial magnetic moments of Ni(IV), which is intrinsically nonmagnetic wi

The material properties of metal oxides are sensitive to even low levels of cation doping, and the local atomic structures around such trace elements in a crystal will differ from the bulk structure due to the different ionic size and electron config
