Fabrication and Investigation of Structural and Magnetic Properties of MnFe2O4 Ferrite Nanoparticles by Sol-Structural Microwave-Assisted Sol-Gel Methods

In this paper, Cadmium doped Mn ferrite nanoparticles ( MnFe2-xCdxO4) was prepared by tow method (1) sol-gel andannealing in electric furnace; (2) microwave-assisted sol-gel using Fe(No3)3.9H2O, Mn(No3)2.4H2O, Cd(NO3)2.4 H2Oand C6H8O7.H2O as a precursors. Structural and magnetic properties of sample have been investigated using XRD,FESEM measurement. The XRD results show that the sample have spinel structure. The FESEM image show the averageparticle size for tow methods about 40 and 30 nanometer for the samples, respectively. The average crystallite size ofsample, which is found from Scherrer formula for tow methods about 3-4 and 13-28 nanometer, respectively.
