Magnetic feature, compositional and structural analysis of the La2SrFe2CoO9 complex perovskite
In this work, we report the synthesis and characterization of the new La2SrFe2CoO9 triple perovskite material. Samples were produced by the solid state reaction method from high purity precursor powders of La2O3, SrCO3, Co2O3 and Fe3O4. XRD pattern was analyzed by Rietveld refinement through the GSA...

| description | In this work, we report the synthesis and characterization of the new La2SrFe2CoO9 triple perovskite material. Samples were produced by the solid state reaction method from high purity precursor powders of La2O3, SrCO3, Co2O3 and Fe3O4. XRD pattern was analyzed by Rietveld refinement through the GSAS code, revealing that observed diffraction peaks are indexed, to the complex perovskite system, and showed that La2SrFe2CoO9 crystallizes in an orthorhombic structure, space group Immm (#71). The lattice parameters were a=5.4314(3) , b=5.4583(3) and c=7.7018(2) . SEM micrographs evidence a strongly diffused granular morphology with mean grain size of 1 μm and EDX spectra show that the chemical composition of samples are in good agreement with the nominal values of the stoichiometric formula. Measurements of magnetization as a function of temperature permitted to determine the ferromagnetic characteristic of material with an effective magnetic moment of 6.18 μB, which is in agreement with the value calculated from the Hund's rules. |
