Structural, Morphological, Optical and Electrical Properties of Y3+ Doped Ni1-x Cdx Fe2-y O4 Spinels Nanoferrite

Structural, morphological, optical and electrical properties are investigated Y3+ doped Ni1-x Cdx Fe2-y O4 spinel nanoferrite (where x = 0, 0.2, 0.4, 0.6 and y = 0 and 0.075) were obtained by sol-gel autocombustion techniques. Nanophase samples were carried out at low temperature and cost effective method with analytical grade metal nitrate. Citric acid was used as a fuel. The prepared powder were sintered at 400 oC and characterized by X-ray diffraction (XRD), Energy dispersive X-ray spectroscopy (EDAX) for structural property, scanning electron microscopy (SEM), Transmission electron microscopy (TEM) for morphological studies and absorption spectra studied using infrared (FTIR) characterization. Ferrite formation was found to quite sensitive. The particle size was determined using Scherers formula and it found that it decreases with increase in Y3+ content. Also DC resistivity increases with increasing Y3+ content and electrical conductivity increases with temperature increases. These results may be applicable for promising area such as high frequency electrical devices.
