Influence of Ni substitution on structural, morphological, dielectric, magnetic and optical properties of Cu–Zn ferrite by double sintering sol–gel technique
Polycrystalline NiCuZn ferrite (NixCu0.3Zn0.7−xFe2O4; x=0.2, 0.3, 0.4 and 0.5) were prepared through sol–gel auto combustion method applying double sintering technique. Structural, morphological, elemental analyses (EDS), Fourier-transform infrared spectroscopy (FTIR), Direct Current (DC) electrical...

| description | Polycrystalline NiCuZn ferrite (NixCu0.3Zn0.7−xFe2O4; x=0.2, 0.3, 0.4 and 0.5) were prepared through sol–gel auto combustion method applying double sintering technique. Structural, morphological, elemental analyses (EDS), Fourier-transform infrared spectroscopy (FTIR), Direct Current (DC) electrical resistivity, dielectric, magnetic and optical properties of prepared samples were analyzed. XRD profiles reveal the formation of simple cubic spinel structure without any traceable impurity. The average crystallite size lies within the range of 22–29nm. Lattice parameter decreases with increasing Ni concentration. Room temperature DC resistivity was recorded from 6.39×105 to 3.79×105Ωcm. Both dielectric constant (ε̇) and loss factor (tanδ) were decreased with increase of frequency while AC conductivity increases. FTIR absorption peak occurred at three different frequency ranges at 570–577cm−1, 1635–1662cm−1 and 3439–3448cm−1. Magnetic properties were investigated by using vibrating sample magnetometer (VSM). Decreasing trends were observed for saturation magnetization (Ms), magnetic coercivity (Hc) and remanant magnetization (Mr) with the increase of Ni content. Optical band gap (∼2.70–2.79eV) were calculated from diffuse reflectance data by using Kubelka–Munk function. |
