Highlights: ► Novel system ZnMn{sub 1−x}Ti{sub x}FeO{sub 4} synthesized by sol–gel route. ► Nanocrystalline materials. ► Magnetic materials. - Abstract: Nanocrystalline ZnMn{sub 1−x}Ti{sub x}FeO{sub 4} (1.0 ≥ x ≥ 0) ferrites were prepared by sol–gel route. Formation of single phase cubic spinel structure for all the compositions was confirmed from their X-ray diffraction patterns. The lattice parameter shows an increasing trend with the increase in Ti content. These ferrite samples existed as crystalline nanoparticles of about 30–40 nm size as observed from transmission electron microscopy (TEM) technique. EDAX analysis indicated that the concentration of different elements in different compositions is in close agreement with the starting concentrations. Infrared spectra showed two main absorption bands in the range 400–800 cm{sup −1} arising due to tetrahedral (A) and octahedral (B) stretching vibrations. The magnetic studies indicated that, the ferrimagnetic behavior increases with titanium substitution.
