The present study is investigated for Cu doped series of Zn1?em class="a-plus-plus">x Cu x FeCrO4 (0.0?≤?em class="a-plus-plus">x?≤?.0) system prepared by sol–gel auto-combustion method. The as-claimed novelty of this route is in situ oxidizing environment of nitrate ions in gel increases rate of oxidation by lowering the decomposition temperature of component. The completion of solid state reaction was checked by thermogravimetric analysis while crystalline phase evolution was assessed by X-ray diffraction. All the compounds exhibit cubic spinel symmetry and lattice constant shows nonlinear behavior with copper content. A morphology of the grains formed was found by scanning electron microscope while element compositions by elemental dispersive X-ray spectroscopy. Infra-red spectral studies showed two fundamental bands correspond to the intrinsic vibrations of tetrahedral and octahedral complex. The results indicate that system transfers from normal to inverse spinel.
