Crystal Structures at Atomic Resolution of the Perovskite Related GdBaMnFeO5 and Its Oxidized GdBaMnFeO6

Perovskite-related GdBaMnFeO5 and the corresponding oxidized phase GdBaMnFeO6, with long-range layered-type ordering of the Ba and Gd atoms have been synthesized. Oxidation retains the cation ordering but drives a modulation of the crystal structure associated with the incorporation of the oxygen at...
