This study examined the crystallographic and magnetic properties of vanadium-substituted lithium cobalt titanium ferrite, Li_0.7Co_0.2Ti_0.2V_0.2Fe_1.7O₄. Ferrite was synthesized using a conventional ceramic method. The samples annealed below 1040 ^oC showed X-ray diffraction peaks for spinel and other phases. However, the sample annealed above 1040 ^oC showed a single spinel phase. The lattice constant of the sample was 8.351 Å, which was relatively unaffected by vanadium-substitution. The average grain size after vanadium- substitution was 13.90 μm, as determined by scanning electron microscopy. The Mössbauer spectrum could be fitted to two Zeeman sextets, which is the typical spinel ferrite spectra of Fe³⁺ with A and B sites, and one doublet. From the absorption area ratio of the Mössbauer spectrum, the cation distribution was found to be (Co_0.2V_0.2Fe_0.6)[Li_0.7Ti_0.2Fe_1.1]O₄. Vibrating sample magnetometry revealed a saturation magnetization and coercivity of 36.9 emu/g and 88.6 Oe, respectively, which were decreased by vanadium-substitution.
