Title: Influence of Ni substitution on structural and magnetic properties of Zn{sub 0.85−x}Ni{sub x}Mg{sub 0.05}Cu{sub 0.1}Fe{sub 2}O{sub 4} ferrite

Nano-crystalline Zn{sub 0.85−x}Ni{sub x}Mg{sub 0.05}Cu{sub 0.1}Fe{sub 2}O{sub 4}, (x = 0.0, 0.17, 0.34, 0.51, 0.68 and, 0.85), were synthesized by sol gel auto combustion method and, effect of Ni content on structural and magnetic properties is studied by x-ray diffraction (XRD) and, magnetic measurements. XRD confirms the formation of single phase spinel ferrite, with Scherrer's grain diameter ranging between 18.95 nm to 33.85 nm. Experimental and theoretical lattice parameter values suggest that the estimated cation distribution is close to the real distribution. Change in Ni-content leads to variation in cation distribution at site A, B and, migration of Cu{sup 2+} ion from B to A site. Ni{sup 2+} ion remains at both A and B site, but when Zn is fully replaced by Ni, it totally goes to A site. Coercivity and anisotropy constant values respectively ranges' between 251.2 to 372.4 Oe and 0.06 × 10{sup 5} to 0.80 × 10{sup 5} erg/cc. Best magnetization value of 43.7 emu/g was obtained for × = 0.68. Variation of magnetic properties can be understood in terms of observed changes in cation distribution.
