Abstract
- Structural and <superscript>57</superscript>Fe MÖssbauer study of Sol-Gel prepared Indium substituted Cobalt ferrites with chemical formula CoFe<subscript>2-x</subscript>In<subscript>x</subscript>O<subscript>4</subscript> (x= 0, 0.2, 0.4, 0.6 and 0.8) are reported in this paper. From the Rietveld refinement of X-Ray diffraction patterns, it is observed that x=0, 0.2 samples are formed in single phase without any detectable impurity and x=0.4, 0.6 and 0.8 samples consists of a relatively small fraction un-reacted Fe<subscript>2</subscript>O<subscript>3</subscript> as an impurity phase. It is also found that lattice parameters increase with the increase of Indium concentration. The SEM images exhibit the increase of grain size from 100-205 nm with the increase of Indium doping concentration. Room temperature <superscript>57</superscript>Fe Mossbauer spectroscopy confirms the magnetic ordering of Fe<superscript>3+</superscript> spins in all the samples. [ABSTRACT FROM AUTHOR]
