Analysis of the electrical transport, conductivity, and dielectric relaxation behavior of La0.75 Ba0.10 Sr0.15 Fe O2.875-δ (δ = 0.375 and 0.50) brownmillerite oxides

The topotactic reduction of La 0.75 Ba 0.10 Sr 0.15 FeO 2.875 with titanium metal leads to a new isostructural material of the composition La 0.75 Ba 0.10 Sr 0.15 FeO 2.875-δ ( δ  = 0.375 and 0.50). XRD analysis of phases confirms that the obtained compound adopts a brownmillerite-type structure. A...
