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, electrical characteristics were assessed using the XRD, FTIR, UV-vis, four probe I-V methods, respectively. XRD pattern verified cubic crystal structure. For both kinds samples, average crystallite size between 23.2 25.6 nm. presence tetrahedral band demonstrated by FTIR spectra. As percentage Co2+ increased, Eg found be 2.70 eV 2.57 eV. DC resistivity values 5.01 x 106 1.26 107 ohm-cm proved that synthesized samples may utilised in transformers reduce their eddy current losses.

Abstract Graphene nanoplatelets (GNPs) offer excellent support for a diverse array of composite applications. Herein, Co 0.5 Mg Fe 1.8 La 0.2 O 4 (CMFL) and its composites were prepared by the sol–gel autocombustion method. X‐ray diffraction confirmed formation single‐phase structure, with both average crystallite size (34.33–46.30 nm) lattice constant (8.292–8.411 Å) increasing GNP insertion. The presence graphene in nanocomposites was Raman spectroscopy, which revealed D band at 1376.38 cm −1 . Fourier transform infrared spectra indicated existence absorption bands corresponding to tetrahedral (534.46–525.94 ) octahedral (456.62–454.95 structures. optical bandgap energy ( E g varied when compositions samples changed, lowest value being 2.58 eV CMFL/2.5 wt.% GNPs. DC electrical resistivity increased from 6.73 × 10 1.07 6 Ω cm, indicating that materials might be appropriate use transformers telecommunications devices. With frequency, dielectric loss decreased, whereas AC conductivity improved. Cole–Cole behavior showed conduction mechanism had non‐Debye relaxation characteristics. saturation magnetization 25.86 42.75 emu/g synthesized samples, coercivity demonstrated variable trend.
