Monodisperse Ni-Zn ferrites (NixZn1-xFe2O4) microspheres have been synthesized via solvothermal method. X-ray diffraction pattern (XRD), transmission electron microscope (TEM), field emission-scanning electron microscopy (FE-SEM) and vibrating sample magnetometry are used to characterize the shape, structure, size and magnetic properties of the as-synthesized magnetic microspheres. The powder XRD patterns revealed the formation of the single phase spinel structure for the synthesized materials. TEM and FE-SEm show the size and morphology of the as-synthesized sample in detail. The maximum magnetic saturation value of the Ni0.2Zn0.8Fe2O4 microspheres can reach 60.6 emu g(-1). These magnetic NixZn1-xFe2O4 microspheres are expected to have wide applications in bionanoscience and electronic devices technology. (C) 2010 Elsevier B.V. All rights reserved.
