Abstract
Nickel – Cadmium ferrites having the chemical formula (Ni1-xCdxFe2O4), (0 ≤ X ≤ 0.5) were prepared by using powders technology method. The particle size of the ferrite samples were estimated from X-ray diffraction studies after the confirmation of the formation of single phase spinel structure of the ferrites. We found that the Lattice constant and density (ρx-ray) increased with Cd content while the porosity was noticed to decrease. Also the magnetic testing showed decreases in values the Coercive Force from (0.408 KA/m) to (0.384 KA/m) and the Remnant Magnetization from (0.056 Tesla) to ( 0.048 Tesla) and the Magnetic Relative permeability is the within range (0.137 ~ 0.125) with increasing of the Cadmium concentration while the Magnetic Susceptibility was noticed to increase from (0.862) to (0.875).
