Structural and Magnetic Property Studies of Nanocrystalline Co0.8Zn0.2Fe2O4

Abstract

The synthesis of Co_0.8Zn_0.2Fe₂O₄ nanoparticles has been achieved by a simple thermal decomposition method from the inorganic precursor, Co_0.8Zn_0.2Fe₂(cin)₃(N₂H₄)_4, which was obtained by a novel precipitation method from the corresponding metal salts, cinnamic acid and hydrazine hydrate. The precursor was characterised by hydrazine and metal analyses, infrared spectral analysis and thermo gravimetric analysis. The thermal decomposition of Co_0.8Zn_0.2Fe₂(cin)₃(N₂H₄)₄ yielded Co_0.8Zn_0.2Fe₂O₄ nanoparticles, which were characterised for their size and structure using X-Ray Diffraction (XRD), High Resolution Transmission Electron Microscopic (HRTEM), Selected Area Electron Diffraction (SAED) and Scanning Electron Microscopic (SEM) techniques. The magnetic property of Co_0.8Zn_0.2Fe₂O₄ nanoparticles was analysed by using Vibrating Sample Magnetometer (VSM).
