Abstract
Solid state reaction has been used successfully to prepare the spinel ferrite Cu0.6Ni0.4Fe2O4. The cubic structure of the sample was discovered by XRD crystal structure analyses. The Rietveld Refinement was used to further refine the XRD spectra, and all of the structure-related data were acquired, confirming the cubic (Fd-3m) structure. The calculated particle size was 91 nm. Five active Raman modes were visible in the Raman spectra, confirming the spinel structure. Raman analysis of the produced samples provided evidence of the lattice structure. Employing Fourier transform infrared (FTIR) spectroscopy, the sample formation was further confirmed. Compositional studies revealed that all the integral elements of the sample are present and there is no trace of impurity whereas morphological analysis infers the dominance of agglomeration phenomenon. The dielectric properties were investigated which were exceptionally good. Optical bandgap studies revealed wide band nature of the materials.
