The B-site substituted perovskite oxides A 2 B′ B ″O 6 have in the recent decades gained
an increasing amount of interest due to their various interesting properties and possible …

Solid oxide fuel cells (SOFC) are highly efficient energy conversion devices with the
advantage of directly utilizing hydrocarbon fuels. Starting with a short introduction about the …

Double-perovskites Sr2MMoO6 (M= Co, Ni) have been investigated as anode materials for a
solid oxide fuel cell. At room temperature, both Sr2CoMoO6 and Sr2NiMoO6 are tetragonal …

An uncommon oxygen absorption/desorption behavior is reported for the cation-
stoichiometric cobalt oxide, YBaCo4O7, structurally composed of two kinds of layers of …

We have investigated a series of double-perovskite oxides Sr2MMoO6− δ (M= Mg, Mn, Fe,
Co, Ni, Zn) for redox stability, oxygen content and crystal structure. Phases with M= Co, Ni …

Modification of the double perovskite Sr2MgMoO6− δ by La substitution has shown that Sr2−
xLaxMgMoO6− δ with 0.6⩽ x⩽ 0.8 has better performance as the anode of a solid oxide fuel …

Here we show that the low-temperature oxygen-storage capability of RBaCo4O7+ δ (R= Y,
Dy, Ho, Er, Tm, Yb, and Lu) depends on the size of the rare earth constituent R. For all these …

Double perovskite Sr2FeMoO6 was prepared by two ways consisting in sol–gel technique
and solid-state reaction method. The resulting powders from gel and mixed oxides …

With the aim of determining and distinguishing the influence of rare-earth doping on the
strength of magnetic interactions, magnetic and magnetocaloric properties of Sr 2-x Pr x …

Sr 2 FeMoO 6 samples with various degrees of Fe, Mo ordering were prepared from a sol-
gel-derived precursor with a sample-encapsulation technique. The order parameter ξ for Fe …
