Glycine-assisted combustion method was used to synthesize the garnet Dy3Fe5O12 nanoparticles. The detailed chemical redox reaction of these garnet nanoparticles are discussed elaborately. The phase and purity of the samples determined using X-ray powder diffraction studies, reveals that the samples form an pure phase cubic crystal structure (space group, Ia3d) at 1100 °C with average crystallite size of 90–97 nm. FTIR confirms the formation of garnet type structure in the region of 500–700 cm–1 wavelength corresponding to the stretching vibration of metal-oxygen group. The chemical elements and oxidation states of these nanoparticles have been investigated by X-ray photoelectron spectroscopy analysis acquired with Al K radiation. The high resolution XPS spectrum of Dy 4d, Fe 2p and O 1s was analyzed. It reveals the presence of single oxidation state of Dy ion (Dy3+) and mixed valence state of Fe ions (i.e., Fe2+ and Fe3+). Scanning electron microscopy was used to study the surface morphology of these nanoparticles and shows spherical shaped grains. From MH loop, the prepared samples exhibit ferromagnetic behavior with the higher value of M s due to the presence of Fe2+ ion. Therefore, the prepared samples are favorable for security and switching applications.
