Abstract

The impact of metal ion substitution on the characteristics of cobalt ferrite nanoparticles is investigated in this work. Sol-gel auto-combustion was used to insert copper (Cu), nickel (Ni), and zinc (Zn) into the spinel lattice. The goal of the study is to comprehend the effects of these substitutions (CuCoFe, NiCoFe, and ZnCoFe) on the magnetic, spectral, and structural properties of the resultant nanoparticles. For every synthetic sample, the successful development of a cubic spinel phase has been confirmed by X-ray diffraction examination. The estimated crystallographic size is roughly 25 nm. The spinel structure's octahedral and tetrahedral sites exhibit metal-oxygen vibrations, as shown by a peak seen at 433 cm⁻³ using Fourier Transform Infrared (FTIR) spectroscopy. Cobalt ferrite nanoparticles replaced with Cu and Ni exhibit well-defined ferromagnetic behavior as revealed by magnetic characterisation. The Zn-substituted sample, on the other hand, displays a paramagnetic hysteresis loop. These findings, along with the results of the other characterization methods, strongly imply that copper, nickel, and zinc have successfully replaced cobalt ions in the octahedral positions of the cobalt ferrite lattice.
