Abstract
Abstract Crystallography information files (CIF) were designed formed CoxCu1−xFe2O4 solid solution with the substitution factor x=0 to 1 with an increment of 0.1 depending on Vegard's law by using crystallography software. The effect of the substitution factor has been studied on some parameters and properties of the Co-Cu ferrite system, such as the effect of substitution factor on the lattice parameter, the volume of unit cell, and the density of the unit cell. Also, XRD patterns were estimated by crystallography software depending on the mathematical models of XRD. The XRD results showed a slight shift in the peak position varying with the substitution factor, these are due to the change in lattice parameter caused by the substitution of ions with different ionic radii. XRD also showed an increment in peak intensity varying with the substitution factor, that's due to an increase in the concentration of Cu which led to an increase in the density of electrons.

Ferritesare ferromagnetic oxide have a wide range of applications in material science due to their magnetic properties [1, 2]. ferrite is classified as hard and soft ferrite depending on its permanent magnetization and the value of the coercive field [2, 3]

Summary
Ferritesare ferromagnetic oxide have a wide range of applications in material science due to their magnetic properties [1, 2]. ferrite is classified as hard and soft ferrite depending on its permanent magnetization and the value of the coercive field [2, 3]. Spinel ferrite is classified as normal ferrite with the formula AFe2O4 and the inverse spinel ferrite with the formula [Fe+3]Tetrahedral void[Fe+3A+2]Octahedral voidO4 according to the Crystal field stabilization energy (CFSE)[14,15,16] and the spin state in the d orbital of the A and B sites of the spinel [15, 17]. In this study, it will focus on CoFe2O4 which has an inverse spinel and substitute of Cu with various concentration and its effect on the crystal structure, XRD, and density
