Synthesis and Characterization of Copper Substituted Lithium Nano Ferrites by Sol-Gel Auto combustion

Abstract

In this work sol-gel method used for preparing nanoscale iron oxide ferrites dopant by copper and lithium, which carries the chemical formula Li 1-x Cu x Fe 5 O 8 where x is the added ratio as molar ratio (x = 0,0.1,0.2,0.3,0.4,0.5,0.6 and 1), during the self-combustion for sol-gel which happen at temperature of 200 o C, after that the samples were divided into four groups , the first group namely that have not been annealed while the other groups ; the second, third and fourth were annealed at 500 o C , 700 o C and 900 o C respectively. In this work the crystalline structure have a dominate phases which have been studied by using the X-ray diffraction as well as
