The Analysis of Cu1-xNixFe2O4 Nanoferrites' Structural, Morphological, Optical, and Magnetic Characteristics

The research centered on utilizing the co-precipitation method to explore the consequences of Ni2+ substitution within Cu1-xNixFe2O4 (0 ≤ x ≤ 1) nanoferrites. This encompassed an examination of their physical and chemical attributes spanning structure, form, optics, and magnetism. Laboratory specimens indicated the exclusive development of spinel crystalline structure through XRD analysis, albeit with minor impurities. Outcomes demonstrated that Ni2+ substitution in Cu1-xNixFe2O4 prompted a reduction in particle dimensions from 20 to 11 nm, while the unchanging lattice measure exhibited a gradual reduction from 8.362 to 8.345 8 Å with amplified Ni2+ ion concentrations. Particle dimensions evaluated by TEM micrographs were akin to those from XRD-tested lab-created samples. Furthermore, FTIR spectra enabled the identification of predominant metal-oxygen bonds within Cu1-xNixFe2O4, unveiling an augmentation in the band gap of nanoferrites from 3.32 to 3.62 eV, attributed to heightened Ni2+ ion content. Conversely, the magnetic attributes of nanoferrites at room temperature were probed using a superconductive quantum interferometer (SQUID) arrangement, exposing an augmentation in copper ferrite's magnetic properties aligned with intensified Ni2+ ion prevalence.
