Does Ti+4 Ratio Improve the Physical Properties of CdxCo1−x+tTitFe2−2tO4?
The microstructure and magnetic properties of Ti substituted CoCd ferrites of the general formula CdxCo1−x+tTitFe2−2tO4, x = 0.20, 0.00⩽t⩽0.25 have been reported. The ferrite samples were prepared by standard double sintering ceramic technique and structural analysis was carried out using X‐ray diffraction. The spinel structure is confirmed for all concentration. Some physical properties (such as lattice parameter, density and porosity) have been also calculated. Temperature and magnetic field dependence of susceptibility is illustrated for all Ti contents. Both experimental and theoretical values of the effective magnetic moment were increased with increasing Ti content. The Curie temperature increases with the addition of Ti up to t = 0.15 after which it decreases. The effect of mechanical pressure on the dc resistivity at room temperature enhances the use of the samples in some applications.
