Ferrimagnetic ionic crystalline materials, with general formula AB 2 O 4 are termed as spinel phase ferrites. Electro – magnetic properties, concentration of different ions and surface morphology of mixed–metal oxides shows significant applications in the various fields. In above work, Cu doped Zn ferrialuminate were prepared by sol-gel auto-combustion route. Purity of the synthesized materials were confirmed by XRD analysis which reveals the formation spinal phase structure and by applying the Debye-Scherer’s formula. Nanocrystalline nature of the samples were studied by transmission electron microscopy (TEM). The particle was found in the nanorange. The temperature dependent DC electrical conductivity was studied by two probe method. Semiconductor behavior with the rise in temperature were found in all the samples.
