In this paper, the preparation of compounds, Ni0.95CoxCu0.05Fe2O4) by using powder technology method where (X = 0, 0.01, 0.02, 0.03, 0.04,and 0.05) annealing at 1100 C temperature for four hours. A series of samples were carried out for the study of structural properties by measuring x-ray diffraction (XRD). It included the study of the lattice constant (a), the particle size (D), the porosity (P) and the virtual density by x-ray diffraction, (x-ray density) as well as the study of Dielectric properties using the LCR , the study of the loss of dielectric meter tand and the electric conductivity (Ϭac). The results of X-ray diffraction showed that all samples had a crystalline,) and also showed that the Lattice constant (a) increases as the content of cobalt increases the density of the particles calculated by X-ray diffraction increases with the cobalt content, while the porosity and particles size decreases as the cobalt content increases, and the electrical show that the real and imaginary dielectric and electrical conductivity using current decreases as frequency increases, the real electrical dielectric constant increases as the cobalt content increases, while the imaginary part of dielectric constant and electrical conductivity decreases as the cobalt content increases.
