Abstract
Nanoferrites of Ni0.1Cu0.2MgxZn(0.7-x)Fe2O4(x = 0.0, 0.15, 0.25, 0.35, 0.45, 0.55 and 0.70 wt%) system fabricated using flash auto combustion technique. All investigated samples annealed for 2 h at 600 degrees C. XRD, FTIR and TEM were utilized to evaluate the structural characterization of as-prepared samples. The electrical DC resistivity of the investigated samples is evaluated as a function of frequency and temperature. The initial magnetic permeability (mu(i)) is dependent on the temperature and was measured at constant frequency 1 kHz and 10 kHz of the sinusoidal wave. A single-phase of spinel structure was formed and with increasing Mg content the peak (311) of 100% intensity decreases, which demonstrates the presence of Mg, which slows down the growth of the crystal as X-ray result. The FTIR spectra of the prepared ferrite samples are distinguished by the presence of two strong absorption bands (nu(1) = 554 cm(-1)) and (nu(2) = 449 cm(-1)). The morphological observation is determined by the transmission electron microscopy (TEM) and shows that the particles size ranged between 26 and 39 nm. It can notice shifted Curie temperature (T-c) to a higher temperature by increasing Mg content. Mass attenuation coefficient (mu(m)), mean free path (lambda), half value layer (X-1/2), tenth value layer (X-1/10) and effective atomic numbers (Z(eff)) for the studied samples, have been simulated using FLUKA (2020.0beta.2), while energy change from 15 x 10(-3)to 15(3+) keV with increasing Mg concentration, both mu m and Zeff decrease. The largest value of mu m and Zeff whenx = 0% while samplex = 0.35% has a minimum value of lambda,X(1/10)andX(1/2).
