| Abstract | ||
| Co(1-x)ZnxFe2O4 (x = 0-0.5) nanocrystalline powders were prepared by co- precipitation method. The crystal structures and magnetic properties of the samples products were identified by x-ray diffractometer and vibrating sample magnetometer, respectively. XRD analysis reveals that Co(1-x)ZnxFe2O4 nanocrystalline powders occurred during a cubic spinel structure. The vibrating sample magnetometer investigations indicate that the saturation magnetization and the magnetic moment values increase with increasing Zn-content. The increase of saturation magnetization and magnetic moment is related to the strong magnetic property of Zn2+. The coercive field of the samples varies linearly from 1137.77 Oe to 33.31 Oe. The decrease of coercive field is ascribed to the decrease in the content of Co2+ on the B sites. The results show that x = 0.5 in Co(1-x)ZnxFe2O4 is an optimum composition with superior magnetostrictive properties for many applications. | ||
