      Ferrite samples with composition, Cd𝑥Co1−𝑥Fe2O4 (𝑥 = 0.80, 0.85, 0.90, 0.95 and 1.0), were prepared by standard ceramic method and characterized by XRD, IR and SEM techniques. X-ray analysis confirms the formation of single phase cubic spinel structure. Lattice constant and grain size of the samples increase with increase in cadmium content. Bond length (A–O) and ionic radii (𝑟A) on 𝐴-sites increase, whereas bond length (B–O) and ionic radii (𝑟B) on 𝐵-site decrease. The crystallite sites of the samples lie in the range of 29.1–42.8 nm. IR study shows two absorption bands around 400 cm-1 and 600 cm-1 corresponding to tetrahedral and octahedral sites, respectively.
