Abstract
Mossbauer spectra of La1−xBa x FeO3−y recorded at room temperature for various values of x show a six-line and/or a single-line subspectrum. The six-line subspectrum with IS=0.41 mm/s and H=52 T results from an orthorhombic perovskite containing only Fe3+ ions. The single-line subspectrum at 0.17 mm/s from a cubic perovskite can be assigned to neither Fe3+ nor Fe4+ but to an intermediate valence state, which may be due to electron hopping between the Fe3+ and Fe4+ ions on the identical octahedral sites. The temperature dependence of electron hopping in the compound La0.40Ba0.60FeO3−y is presented.
