Abstract
- Structural, magnetic and 57Fe Mössbauer investigations of indium (In) doped cobalt ferrite are reported. Polycrystalline CoFe 2−x In x O 4 , x = 0, 0.2, 0.4, 0.6, 0.8 samples are prepared by sol–gel method. In contrast to most of the literature, in the present work phase pure samples are obtained, except for x = 0.2. The presence of ferrimagnetic ordering in all the samples is confirmed from in-field 57Fe Mössbauer spectroscopy measurements. The cation distribution is obtained unambiguously from the combined analysis of Raman and in-field 57Fe Mössbauer spectroscopy measurements. The variation of magnetic moment values calculated from the obtained cation distribution are found to match qualitatively with the experimental values, supporting the analysis of in-field 57Fe Mössbauer and Raman spectroscopy measurements.
