X-ray diffraction (XRD) and transmission electron microscopy (TEM) results have revealed the formation of a single-phase compound with a particle size of 10-20 nm. X-ray absorption near-edge structure (XANES) investigations confirmed the presence of Fe3+, Ga3+ and Co2+ ions in FeCoGaO4. High saturation magnetization (Ms) (-50 emu/g), remanent magnetization (Mr) (10 emu/g) and coercivity (-630 Oe) are observed at 50 K. A lower coercivity (28 Oe), and Mr (0.11 emu/g) are observed at 300 K. The origin of magnetism in the FeCoGaO4 nanoparticles has been mechanistically discussed considering the plausible magnetic interactions among the constituent ions in the material.
