Sol-gel auto-combustion synthesis, cation distribution and physicochemical properties of Ni0.6Cd0.4Fe2O4 NPs

The intent of begun work is to synthesis and study the structural, electric, magnetic and frequency dependent dielectric properties of Ni0.6Cd0.4Fe2O4 NPs fabricated via sol-gel auto-combustion technic. The XRD data affirmed that the synthesized Ni0.6Cd0.4Fe2O4 NPs do possess a single phase; spinel structure; cubic geometry and ferrite in nature. The lattice constant (a) was estimated to be 8.363 A and the crystallite size (t) determined from Debay-Scherrer method was found to be 48.70 nm. SEM images of Ni0.6Cd0.4Fe2O4 NPs may propose the spherically shaped with the formation of fusion in gains. Activation energy (ΔE) determined from the Arrhenius relation was recorded as 0.03 eV. Eventually, comprehensive magnetic parameters viz. (Ms), (Hc), (nB) were shown to be decreased in comparison to the unloaded NiFe2O4 ferrite as an effect on non-magnetic Cd2+ ions over magnetic Ni2+ and Fe3+ ions.
