Abstract
We report synthesis, characterization of Zn1-xNixFe2O4 (x = 0.0–1.0) nano ferrites, by using x-ray diffraction 'XRD', vibration sample magnetometery, UV–Vis spectroscopy. XRD validates the formation of fcc spinel structure. Ni-addition leads to: grain diameter modification; linear decrease of lattice parameter; un-equal distribution of both Ni2+, Zn2+, Fe3+ ions on A, B sites; changes in the degree of inversion, and oxygen parameter showing changes in disorder; linear variation of bandgap; significant reduction of coercivity with simultaneous increase of saturation magnetization. Results clearly demonstrate that Ni-addition in Ni-Zn ferrite can be effectively used to tune magnetic properties, bandgap.
