Abstract

Cobalt-cadmium ferrite nanoparticles have gained the attention of researchers due to their smaller particle size, high saturation magnetization, and high direct current (DC) resistivity. This study aimed to synthesize cobalt-cadmium nano ferrites doped with calcium, zinc, and nickel (CoCd1-xMxFe2O4, where M = Ca, Zn, and Ni) and to study the effect of calcium, zinc, and nickel on the properties of CoCdFe2O4. A chemical co-precipitation technique was used to synthesize the ferrite nanoparticles. Four different samples of cobalt cadmium ferrite nanoparticles were prepared and doped with calcium, nickel, and zinc, respectively. According to XRD analysis, particle sizes vary between 17.39 nm and 27.65 nm and lattice parameters change from 8.34 nm to 8.42 nm. From UV–Visible absorption spectra, the energy bandgap of the ferrite nanoparticles is tuned between 3.24 eV to 3.16 eV. FTIR was used to study the structural and morphological features of the synthesized nanoparticles. The magnetic measurements through VSM analysis showed that the saturation magnetization decreased due to the calcium doping and increased with zinc and nickel doping.
