Synthesis and Charactrization of Ni-Zn Ferrite Based Nanoparticles by Sol-Gel Technique
Department of Fundamental & Applied Science, Universiti Teknologi,PETRONAS,Bandar Seri Iskandar
ABSTRACT
A series of Ni-Zn ferrite based naoparticles (Ni0.76-xZn0.04+x Ti0.0025Co0.1Cu0.075Mg0.04Fe1.96O3.96) in which x is varied from 0.01 to 0.04, were prepared by sol-gel technique. Characterization of the samples was Performed by X-Ray Diffraction (XRD), Raman Spectroscopy, and Field Emission Scanning Electron Microscope (FESEM). The XRD results show the major peak (311) of the spinel cubic structure for Ni-Zn ferrites. FESEM results show that single phase Ni-Zn ferrite nanoparticles with average diameters 17-45 nm can be obtained by sol gel technique. Initial permeability and Q factor for all samples were measured and the magnetic measurements of the nano ferrites show that it can be used as a magnetic feeder for the transmitter.
