STUDY OF THE IR SPECTRAL PROPERTIES OF MAGNETIC IRON OXIDE (FE₃O₄) NANOMATERIALS

Abstract

This study is devoted to the infrared (IR) spectral analysis of Fe₃O₄-based magnetic nanomaterials, focusing on the vibrational characteristics of molecular bonds, structural features, and physicochemical parameters. Infrared spectroscopy is used to identify the internal structure, functional groups, and lattice bonding of the nanoparticles. The IR spectrum of Fe₃O₄ is highly sensitive to particle size, crystal structure, temperature, and synthesis conditions, and these factors determine the material’s potential for practical applications. Therefore, the spectral characteristics of Fe₃O₄ samples obtained under different conditions were comparatively analyzed in this work.
