Magnetic and Structural Properties of Nanocomposite ZnO-Fe₃O₄ Films Prepared by Solid-State Synthesis

Abstract:

A simple method for obtaining ZnO-Fe₃O₄ nanocomposites using solid-state reaction Zn + 3Fe₂O₃ ZnO + 2Fe₃O₄ is suggested. An analysis of the characteristics and properties of ZnO-Fe₃O₄ nanocomposites was carried out by a combination of structural and physical methods (X-ray diffraction, scanning electron microscopy, photoelectron spectroscopy, Mössbauer measurements, X-ray fluorescent analysis, and magnetic measurements). The magnetization of the hybrid ZnO-Fe₃O₄ films is equal to 440 emu/cm³. The resulting Fe₃O₄ nanoparticles are surrounded by a ZnO shell and have sizes ranging between 20 and 40 nm.
