Study on synthesis and characterization of nano scale spinel Mn0.5¬Fe2..5O4 by micro-emulsion method

Abstract

The single phase of Mn0.5Fe2.5O4 spinel crystals was prepared by the micro-emulsion method with the oil phase is DGDE (diethylene glycol diethyl ether). The characteristics of the materials have been determined by the X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX), Scanning electron microscopy (SEM) and Brunaure-Emmet-Teller (BET) nitrogen adsorption and desorption, Vibration sampling magnetometer (VSM), Fourier transform infrared spectroscopy (FTIR). The results showed that the single phase of Fe0.5Mn0.5Fe2O4 crystalline was formed due to the substitution of Fe by Mn in the Fe3O4 crystal lattice and single phase spinel crystal is formed with the size of 6.7 nm, specific surface area ≈ 193 m2.g-1, the saturation magnetization reaches ≈ 27 emu.g-1.
