| المستخلص: | We describe the preparation and characterization of a new double perovskites of formula SrLaFeNi0.5W0.5O6 and CaLaFeNi0.5W0.5O6. It has been obtained in polycrystalline form by thermal treatment. This material has been studied by X-ray (XRD) it crystallizes, at room temperature, in the tetragonal space group I4/m, and shows an almost perfect ordering between Ni2+ and Mo6+/W5+ cations at the B substructure. The infrared spectra of the powders were collected in order to check the formation of the both samples. |
