Effect of D-block element Co 2+ substitution on structural and vibrational properties of spinel ferrites

A series of Cu-C o ferrite based bulk particles (Cu (1-x) Co(x)Fe2O4) in which x is varied from 0.0 to 0.6 were prepared by Solid State reaction route. The influence of the Co content on the structural properties of cubic Nickel ferrites (CuFe2O4) was investigated using Raman spectroscopy. Slight reduction in the lattice parameter of Co doped CuFe2O4 has been observed as compared to the parent CuFe2O4. From Raman scattering spectra, a shoulder like feature has been observed in both parent and doped com pounds which reveals that octahedral site is occupied by Co, Cu and Fe ions and tetrahedral site is occupied by only Feion.
