Title: Structural and Raman scattering study of Ni-doped CoFe{sub 2}O{sub 4}

Abstract

Raman scattering measurements were made on polycrystalline CoFe{sub 2}O{sub 4} and Co{sub 0.5}Ni{sub 0.5}Fe{sub 2}O{sub 4} ferrites as prepared by solid-state reaction route. Rietveld refined X-ray diffraction pattern confirmed the formation of single-phase and both of the samples perfectly indexed in cubic spinel structure with Fd3m space group. Slight reduction in the lattice parameter of Co{sub 0.5}Ni{sub 0.5}Fe{sub 2}O{sub 4} has been observed as compared to CoFe{sub 2}O{sub 4}. From Raman scattering spectra, a shoulder like feature has been observed in both of the compounds reveals that octahedral site is occupied by Co, Ni and Fe ions and tetrahedral site is occupied by only Fe ion.
