ملخص البحث

Mg-ferrite nano particles were prepared by sol gel auto computation. Spinel ferrites of different composition have been studied .The particle sizes were estimated, based on the X-ray diffraction peaks, to be between 25 and 30 nm, and studied the electrical properties and physical properties where Ferrite is a polycrystalline, sintered material with high electrical resistively. ferrites are magnetic materials play a useful role in many technological applications because of their high initial permeability, low magnetic losses, high resistivity, low dielectric losses, mechanical hardness, high Curie temperature and chemical stability ferrites sensitive structure materials and their properties critically depend on the manufacturing process. Because of excellent soft magnetic properties of ferrites so that it used in electronic and telecommunication industries.
