Volume : V, Issue : IV, May - 2015 DIELECTRIC PROPERTIES OF ALUMINIUM SUBSTITUTED MAGNESIUM-COPPER FERRITE BY SOL-GEL METHOD S.B. Lagad , None By : Laxmi Book Publication Abstract : Aluminium substituted magnesium-copper ferrites; Mg0.5Cu0.5AlxFe2-xO4 (0.1 ≤ x ≤ 0.3 with step 0.1) has been synthesized by using the Sol-Gel auto-combustion method to study the effect of Al3+ doping on dielectric properties of ferrites. The samples were characterized by X-ray diffraction Electron Dispersive Spectroscopy (EDS) and scanning Electron Microscopy for structural properties, LCR meter for dielectric parameters and FTIR absorption techniques. The X-ray diffraction data shows that system exhibit a single phase with cubic spinel structure. Lattice constant was found to be decreases with Aluminium concentration due to larger ionic radius of Fe3+ ions replaced by small ionic radius of Aluminium ions. Keywords : Unable to cast object of type 'System.DBNull' to type 'System.String'.
