Synthesis and Characterization of Co 0.8-x Ni x Zn 0.2 Fe 2 O 4 Ferrites by Williamson–Hall and Size–Strain Plot Methods

Abstract

The Co-Zn ferrite (x=0.00) and Nickel doped Co-Zn ferrites (x=0.24) was synthesized by low cost solid state reaction method and characterized by XRD technique. The X-ray diffraction results for the samples showed the formation of single phase cubic spinel. The lattice constant and particle size for Co-Zn ferrite(x=0.00) is found to be 8.3465 Å and 26.72 nm and for Nickel doped (x=0.24) it is 8.3440 Å and 24.21nm. Micro strain ( ε ), Dislocation density(ρ D ), Hopping lengths (L A and L B ), Bond lengths (A - O and B-O), Ionic radii (r A and r B ), Texture coefficients (T hkl ) and Standard deviation (σ) are also reported. The particle size is confirmed by scanning electron microscope (SEM). The Williamson-Hall plot and stress-strain plot also employed to understand the mechanical properties of materials.
