Abstract :

In the present study Mg-Ni-Al ferrites materials were synthesized by wide-eyed ceramic method (solid-state method). The formation of cubic single phase was affirmed by XRD of Mg-Ni-Al ferrite. The variation of lattice constant (a) with dopant aluminum (Al) is assigned to Vegard’s law. The crystallite size(D), lattice constant(a), micro strain(ε), X-ray density (Δx), dislocation density (D) , hopping lengths (LA and LB), Bond length (A-O and B-O) and Ionic radii (rA and rB), also reported. The Williamson-Hall plot and size-strain plot also employed to understand the structural and mechanical attributes of ferrites samples.
