Description
Summary:Cu 2+ substituted Co-Mg and Co-Zn mixed ferrite, nanoparticles with composition Co 0.5 M 0.5-x Cu x Fe 2 O 4 ( x  = 0.0, 0.2 and 0.4) for M = Mg and Zn were produced by a sol–gel method involving auto-combustion. X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) Spectroscopy, Field effect scanning electron microscopy (FESEM) with EDS, Vibrating Sample Magnetometer (VSM), and Probe methods were used for determining the structural, electrical, and magnetic properties, DC electrical resistivity of these ferrites, respectively. The result of the lattice constant, crystallite size, particle size, bond lengths, magnetization, coercivity, and dc resistivity shows these spinel materials to be highly significant in everyday life.
