Analysis crystal structure of magnetic materials Co1-xZnxFe2O4

Abstract

Abstract Modification of zinc substitution cobalt ferrite material is expected to be one of the microwave absorbing material candidates because it has single phase permittivity and permeability. Permitivity and permeability are engineered from the inter-substitution of atoms in the crystal lattice as a function of composition. Substitution of zinc into cobalt ferrite (Co1- xZnxFe2O4) for Zn2+ (x = 0 – 1) has been synthesized using the solid reaction method through mechanical deformation techniques. The results of refinement of X-ray diffraction patterns indicates that a single phase is obtained for all x compositions. Cubic structure formation with Fd3m space group, where the lattice parameter, lattice strain, cell unit volume, and atomic density change as a composition function. Morphological observations of particles using a scanning electron microscope showed that the particle size distribution was evenly distributed for all compositions with particle sizes ranging from 100-500 nm, whereas in each particle the average size of crystallite also changed as a function of composition. It was concluded that the effect of Zn substitution on Co1-xZnxFe2O4 resulted in changes in the crystal structure parameters as a function of composition with a uniform particle size distribution in all compositions.
