Some of physical properties of nanostructured (Mg1-xCoxFe2O4)‎ ferrites prepared by sol-gel method

Abstract EN

Sol-gel auto combustion technique was used to prepare nanoparticles of magnesium-cobalt ferrites with the chemical formula Mg1-xCoxFe2O4 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.
