Ionic and mixed conducting oxides (La_(0.9)Sr_(0.1))[(Ga_(1-x)Fe_x)_(0.8)Mg_(0.2)]O_(3-y) (I) and (Sr_(1.8)La_(0.2))(GaFe)O_(5.1) (II) with the perovskite and brownmillerite structures, respectively, have been prepared in forms of dense bulk ceramics and ceramic coatings by the sol-gel method. Thin films II have been grown by the pulsed laser deposition method on single crystal MgO (100) and Si (100), fused silica, and stainless steel substrates. The films grown under optimal process conditions were single-phase and homogeneous, with a high degree of preferential orientation. The structure and microstructure of the ceramic coatings have been studied by X-ray diffraction and scanning electron microscopy.
