Abstract
Sol-gel auto combustion was used to create a sequence of soft ferrites, NixMg1- xFe1.9Sm0.1O4(x = 0.0, 0.2, 0.4 & 0.6). The XRD, FTIR, UV-vis, & four probe I-V techniques, respectively, were used to evaluate the structural, optical, and electrical properties. The cubic crystal structure was confirmed by the XRD pattern. The range of 25.71 - 33.67 nm was found to be the average crystallite size. FTIR spectra provided evidence of the tetrahedral band's existence. With the enhancement of Ni2+ concentration, Eg was determined from 2.28-3.21 eV. It was confirmed by the ranges of DC electrical resistivity that materials might be used in transformers to lessen eddy current losses.
