Abstract

We present a theoretical and experimental study on the influence of the Ba/Sr and Co/Fe ratios as well as the oxygen-non-stoichiometry on the stability of Ba0.5Sr0.5Co0.8Fe0.2O3 d (BSCF). Thin-layer depositions are analysed by looking at TEM images and EDX spectra. Bondanalytical calculations are performed to explain the stability difference between hexagonal and cubic BSCF. Finally, annealing experiments analysed using XRD give an insight into the differences of phasefraction growth with respect to the Ba/Sr ratio.
