We present the results on atomic and lattice structure of the polycrystalline spinel ferrites system Co{sub 1-x} Ti{sub x}Fe{sub 2}O{sub 4} (x = 0.0, 0.25, 0.50) synthesized by following the conventional solid-state reaction route. The observed X-ray diffraction (XRD) data confirms that all the prepared samples are indexed in cubic crystal structure (space group Fd3m). Diffraction pattern showed TiO{sub 2} phase due to presence of Ti{sup +4} ions. Four Raman active phonon modes are observed for CoFe{sub 2}O{sub 4} sample existing around 295, 462, 585, 689, cm{sup −1} as Eg, T{sub 2g}(2), T{sub 2g}(3), and A{sub 1g}, respectively. With 25 % Ti ion doping, the peak T{sub 2g}(3) disappears, while to that T{sub 2g}(1) emerges. This is an indication of presence of TiO{sub 2} phase in Co{sub 0.75}Ti{sub 0.25}Fe{sub 2}O{sub 4} and Co{sub 0.5}Ti{sub 0.5}Fe{sub 2}O{sub 4} ceramics.
