Some of Physical Properties of Nanostructured (Mg1-xCoxFe2O4) Ferrites Prepared by Sol-Gel Method

Abstract

Sol-gel auto combustion technique was used to prepare nanoparticles of magnesium-cobalt ferrites with the chemical formula Mg_1-xCo_xFe₂O₄ for  (x=0, 0.2, 0.4, 0.6, 0.8, 1), where x added as weight  percentages, and sintering  at temperature (1100 ^oC). The X-ray patterns of prepared powder has confirmed the structure of cubic spinel structure (fcc). The prepared samples were composed of nearly spherical nano particles .An average particle size of  magnesium-cobalt ferrite  were  calculated  using  Debye Scherer’s relation is equal 53.12 nm. The surface structure of the samples was investigated by Scanning Electron Microscope(SEM). The electromagnetic properties for prepared samples were investigated using Vector Network Analyzer (VNA) in X-band microwave region.
