“…The elliptic shape of the ð6 15 3Þ reflection in the reciprocal space map is also an evidence of the strain field in the film. This is consistent with a spread of the a Ã and b values along an hypothetical line (dashed line in the figure) from the calculated position of the ð6 15 3Þ reflection for the reported bulk values [5] (B in the figure) to a fully strained structure with equivalent cell volume and in-plane a Ã parameter equal to the substrate parameter (S in the figure).…”

“…The powder was then ground, uniaxially pressed into pellets, and sintered in air at 1150 C in order to prepare the targets for the ablation experiment. X-ray diffraction (XRD) of the sintered targets confirmed the complete formation of the orthorhombic phase, in good accordance with the reported results [5]. Laser deposited SFO films were prepared by using a Nd:YAG laser with tripled frequency (355 nm wavelength), 9 ns pulse length, 10 Hz repetition rate, and 2-3 J/cm 2 energy density per pulse.…”

“…Even in the presence of the intense substrate peak, it is possible to clearly resolve the reflection from the film. The measured out-ofplane and in-plane cell parameters for the asdeposited film are summarized in Table 1 in comparison to the reported bulk values [5]. In our films the a Ã in-plane values are slightly shorter than reported values for bulk samples, whereas the out-of-plane b-parameter is larger (b ¼ 19:065 ( A).…”

“…The objective of this work is to study epitaxial thin films of Sr 4 Fe 6 O 137d : The bulk material is orthorhombic (Iba2 group) with cell parameters a ¼ 11:104 ( A; b ¼ 18:924 ( A, and c ¼ 5:572 ( A [5]. It has higher stability than ferrite or cobaltite perovskites, and it has shown interesting MIEC properties in bulk ceramic samples [3,6].…”

Mixed-conducting ceramic oxides have potential uses in high-temperature electrochemical applications such as solid oxide fuel cells, batteries, sensors, and oxygen-permeable membranes. The Sr-Fe-Co-O system combines high electronic/ionic conductivity with appreciable oxygen permeability at elevated temperatures. Dense ceramic membranes made of this material can be used to separate high-purity oxygen from air without the need for external electrical circuitry, or to partially oxidize methane to produce syngas. Samples of Sr2Fe3-xCoxOy (with x = 0,0.6,1.0, and 1.4) were prepared by solid-state reaction method in atmospheres with various oxygen partial pressures (pO2) and were characterized by X-ray diffraction, scanning electron microscopy, and electrical conductivity testing. Phase components of the sample are dependent on cobalt concentration and pO2. Electrical conductivity increases with increasing temperature and cobalt content in the material.

Cryst. Res. Technol. 352000 2 151-165Synthesis of InGaZnO 4 at 20Kb and 50Kb produced a single crystal and a twinned crystal respectively. The X-ray diffraction crystal structure refinement (R1 = 0.015 and 0.019 respectively) and the Charge Distribution analysis are reported. Space group is  R3m; cell parameters in hexagonal axes are a = 3.2990 (2)Å, c = 26.1013(25)Å (20kb single crystal) and a = 3.3051(2)Å, c = 26.1029(19)Å (50kb twinned crystal). The cell volume is 246.01(3)Å 3 and 246.94(3)Å 3 respectively. The In is in regular octahedral coordination, whereas Ga/Zn are in trigonal bipyramid co-ordination. Charge Distribution on cations (2.94 and 2.95 respectively vs. 3.0 for In, and 2.53 vs. 2.5 for Ga/Zn) shows that the structure is well refined. Charge Distribution on oxygens (-1.96 and -2.04 for O1 and O2, vs. -2.0) excludes the presence of valence unbalance effects. A possible structural role of the trigonal bipyramidal coordination is discussed.
