In this paper, manganese ferrite nanoparticles of controlled size were synthesized using chemical co-precipitation method and characterized for its structural and magnetic properties. The method is relatively simple, low cost and their particle size can be easily controlled. The X-ray diffraction pattern confirms the synthesis of single crystalline phase of MnFe2O4 nanoparticles with lattice parameter 8.5075Å. From TEM analysis it is seen that the sample contains nanoparticles of almost spherical in shape with the average particle size of 5 nm. The HRTEM image of the nanoparticles indicates the single crystalline nature which implies that high quality uniform manganese ferrite is obtained with our facile wet chemical method. Spectroscopic study implies that oleic acid is coated on the surface of the MnFe2O4 nanoparticles. The magnetic measurements show superparamagnetic nature of the sample. The saturation magnetization is 69emu/g. The superparamagnetic nature with high saturation magnetization makes these nanoparticles suitable for the synthesis of ferrofluid.
