The vibrating sample magnetometer demonstrated that the substitution of Fe with Cu in the A and D-sites resulted in a reduction of the saturation magnetization (Ms) from 14.41 to 7.46 emu/g within the range of 0.000 ≤ x ≤ 0.060. X-ray photoelectron spectroscopy confirmed the valence states of Dy, Cu, and Fe as Dy 3+, Cu 3+, Cu 2+, Fe 3+, and Fe 2+. Scanning electron microscopy analysis showed the presence of nanometer-sized grains with a whisker-like shape. Fourier-transform infrared spectroscopy revealed distinct vibrational bands characteristic of DyIG and confirmed the replacement in octahedral and tetrahedral sites. The grain size (71.01–65.51 nm) and lattice parameter (12.38–12.31 Å) decreased as the level of copper doping increased up to 0.06, indicating a significant substitution of copper in the iron sites. X-ray diffraction analysis confirmed that all the samples consisted of garnet-type-cubic crystals and exhibited a nanocrystalline nature. The research investigated how the replacement of iron (Fe) with copper (Cu) ions affects the formation of crystals and magnetic properties in Dy 3Fe 5-xCu xO 12 (with x values of 0.0, 0.2, 0.4, and 0.6) created using the hydrothermal method.
