Abstract
The cobalt zinc ferrite (Co1-xZnxFe2O4 x = 01.0) nanoparticles were synthesized by a hydrothermal method. Effects of zinc content and synthesis time on the microstructure and magnetic property of the nanoparticles were studied. The experimental results indicated that Zn2+ substitution for Co2+ and different synthesis time lead to obvious changes in microstructure and magnetic property of the ferrites. The saturation magnetization of the nanoparticles showed maximal value for the Zn content x = 0.2 and overall increased as increasing synthesis time form 12 hrs to 24 hrs. The residual magnetization, the coercivity and anisotropy constant had similar variation trends with shape anisotropy as varying Zn content.
