Abstract

Coprecipitation method was used to create a sequence of Cd₀.₆Mg₀.₄Fe₁.₉Ho₀.₁O₄ and Cd₀.₆Mg₀.₂Co₀.₂Fe₁.₉Ho₀.₁O₄ soft ferrites. The structural, optical, and electrical characteristics were assessed using the XRD, FTIR, UV-vis, and four probe I-V methods, respectively. XRD pattern verified the cubic crystal structure. For both kinds of samples, the average crystallite size was between 23.2 and 25.6 nm. The presence of the tetrahedral band was demonstrated by FTIR spectra. As the percentage of Co2+ increased, Eg was found to be 2.70 eV and 2.57 eV. DC electrical resistivity values of 5.01 x 106 and 1.26 x 107 ohm-cm proved that synthesized samples may be utilised in transformers to reduce their eddy current losses.
