Study of Magnetic Behavior of Mn1-xNixFe2O4 Nanoparticles

The nano crystalline manganese nickel cobalt ferrite is synthesized by a simple technique of thermal evaporation with the help of egg white and its magnetic behaviour is analyzed for different annealing temperature. The saturation magnetization for MnNiFe2O4 at different annealing temperature has been recorded and also the influence of particle size in magnetic properties is analyzed. The FT-IR spectra of the sample reveal the common feature of ferrites like high frequency band to the tetrahedral and low frequency band to the octahedral stretching vibrations. The presence of constituent phases in MnNiFe2O4 is confirmed by X-Ray Diffraction. The particle size, morphology and percentage of composition elements are measured by employing Transmission Electron Microscopy (TEM),
