Synthesis and structural analysis of Ni_0.45Cu_0.55Mn₂O₄ by Williamson–Hall and size–strain plot methods

This paper describes synthesis and structural properties of Ni_0.45Cu_0.55Mn₂O₄ nanopowder, obtained by co-precipitation route. XRD pattern reveals cubic structure with lattice parameter 8.305 Å. We report crystallite size (D), micro strain (ε), dislocation density (ρ_D), and hopping lengths (L_A and L_B). We also report preferential orientation by texture coefficients [Tc (h k l)]. The Williamson-Hall plot and stress-strain plot also employed to understand the mechanical properties of materials.
