dc.description.abstractA new oxide of the Ruddlesden–Popper series in the (Eu,Sr)n+1(Co,Fe)nO3n+1 system has been isolated and structurally characterized. X-ray diffraction and electron microscopy show that polycrystalline Eu2SrCo1.5Fe0.5O7 constitutes the n = 2 member of a homologous series, the essential feature of which is the existence of two connected Co/Fe octahedral layers with a perovskite-like structure, linked by an EuO rock-salt like layer. Random distributions of 3d-metals in the perovskite blocks and interstitial and oxygen vacancies in the rock-salt layers (anti Frenkel defects) are observed by electron microscopy. Such facts are commonly associated with high electronic conduction and ionic conductivity. The electrochemical study shows that the area-specific resistance of this compound is 0.26 U cm2 at 700 ºC in air, a value which is comparable to those of the best state-of-the-art Ruddlesden–Popper materials used as cathodes in intermediate temperature solid oxide fuel cells.
