Description :
The polycrystalline samples of calcium substituted mixed nanoferrites CaFe12O19, CaCr0.5Fe11.5O19 and CaCr1Fe11O19 were prepared by sol gel auto combustion method in which the urea was used as a fuel. The XRD pattern of prepared samples confirms M type hexagonal single phase crystalline structure. Using XRD analysis, lattice parameters, size of atoms have been determined. The morphological investigations and nanometric sizes of the samples were studied by using scanning electron microscopy. The samples were subjected to study the variation of dielectric constant as well as loss tangent with log frequency. All samples follows the Maxwell Wranglers’ interfacial polarization.
