Tariq A. Al-Dhahir | Bassam T. Al-Azraq

Abstract: CrxCu0.25Zn0.75-xFe2O4 with (x=0.0, 0.25, 0.35, 0.45, 0.55, 0.65, 0 and 0.75) spinal ferrite nanoparticles have been synthesized via sol ? gel auto combustion method. The result powder was calcined at temperature of 850C? for 3 hours. Structural and electrical properties of CrxCu0.25Zn0.75-xFe2O4 were investigated using x ? ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x ? ray spectroscopy (EDS) and LCR meter. XRD pattern of CrxCu0.25Zn0.75-xFe2O4 provides information about single-phase formation of spinal structure with cubic symmetry. SEM technique demonstrated that nanoparticles with grain size found to be in nanometer range. Particle size, lattice constant and porosity decrease with increasing Cr content, while bulk density. Both ?' and ?'' decrease when there is increasing in the frequency, from another side they are increasing when Cr content increased
