Abstract
In this study, Zn substituted cobalt ferrite (Co1−xZnxFe2O4, x = 0, 0.125, 0.25, 0.375, 0.5) nanowires were synthesized by an optimized sol–gel route using anodized aluminum oxide (AAO) template. The structure and distribution of cations in octahedral and tetrahedral sites of spinel structure were determined by X-ray diffraction technique. Furthermore, the morphology and magnetic properties of Co1−xZnxFe2O4 nanowires were investigated by electron microscopy and vibrating sample magnetometry. The coercivity of Co1−xZnxFe2O4 nanowires decreased from 1150 to 170 Oe with Zn2+ substitution while the saturation magnetization initially increased from 69.6 to 80.9 emu/g up to x = 0.125 and then decreased to 47 emu/g for x = 0.5.
