Abstract

57Fe Mössbauer effect (ME) was studied at 295K and 77K on the polycrystalline samples of the spinel oxide system Li 0.5(1+x)Cr0.1Fe2.4-1.5XO4 (x = 0.0 to 0.5) synthesized by double sintering ceramic technique. The chemical stoichiometry of the final products was ascertained by EDAX. The X-ray diffractometry (XRD) showed that all the samples were single-phase cubic spinels. The cell edge parameter, a (Å) for each composition was found by XRD-pattern indexing and using the Nelson-Riley method. The distribution of cations in the spinel was determined through XRD intensity analysis using the computer programme. The saturation magnetization for each composition was recorded using hysteresis loop tracer at the applied field of 4kOe. The Mössbauer spectra exhibit two Zeeman sextets due to different fields at tetrahedral (A) and octahedral (B) Fe3+ ions. The ME parameters are deduced using the NORMOS software and the observed hyperfine interaction parameters are explained in the light of cation distribution determined through XRD, magnetization and Mössbauer spectroscopic studies.
