We have investigated single phase formation in a series of (Sn, Mn)CrFeO produced by low temperature synthesis based on the hydrothermal process in a reflux system and in a stirred pressure reactor. The evolution of the properties is investigated by X-ray diffraction (XRD) and by magnetic measurements. Evidence of successful Sn or Mn incorporation into the corundum structure is obtained. Fe Mössbauer spectra show the materials to be paramagnetic for Fe concentration x≤0.5 and in an ordered magnetic state at higher concentration. Rietveld structure refinement of the XRD spectra is employed in the analysis. [ABSTRACT FROM AUTHOR] |
