In this work, the impact of nonstoichiometric substitution Fe3+ cations by Ni2+ ones on structural and magnetic properties Co0.5Ni0.5+xFe2−xO4 nanoferrites (0.0 ≤ x 0.4) synthesized citric autocombustion method has been investigated. The single cubic phase for samples sintered at 600 °C was verified XRD patterns FTIR spectra. crystallite size microstrain were deduced using Williamson-Hall metho...

A series of Bismuth doped Cobalt nanoferrites of chemical composition CoBixFe2-xO4 (where x = 0.00, 0.05, 0.10, 0.15, 0.20 & 0.25) were prepared by sol-gel combustion method and calcinated at 600 ̊C. The structural and morphological studies were carried out by using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy...

Structural and magnetic properties of Cu 2+ substituted Ni0.8-xCuxZn0.2Fe2O4 ferrites for x = 0.0 to 0.6 with the step increment of 0.2 prepared by an auto-combustion method have been investigated. The X-ray diffraction pattern of these compositions confirmed the formation of the single phase spinel structure. Further, the XRD have been used to calculate the lattice parameter and grain size. Th...

Nanoparticles of Mn0.5Zn0.5-xCdxFe2O4 with x varying from x = 0.0 to 0.3 were prepared by wet chemical co-precipitation method. The structural and magnetic properties were studied by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM) and Electron Paramagnetic Resonance (EPR) technique. ...
