Ba2YFeO5.5: A Ferromagnetic Pyroelectric Phase Prepared by Topochemical Oxidation.
Reaction of the anion-deficient, cation-ordered perovskite phase Ba 2YFeO5 with 80 atm of oxygen pressure at 410 C results in the formation of the Fe4+ phase Ba2YFeO5.5. The topochemical insertion of oxide ions lifts the inversion symmetry of the centrosymmetric host phase, Ba2YFeO5 (space group P2...
