Abstract
Observation of room temperature ferromagnetism in Fe doped In 2O 3 samples (In 1− x Fe x ) 2O 3 (0 ⩽ x ⩽ 0.07) prepared by co-precipitation technique is reported. Lattice parameter obtained from powder X software shows distinct shrinkage of the lattice constant indicating an actual incorporation of Fe ions into the In 2O 3 lattice. X-ray diffraction data measurements show that the entire sample exhibits single phase polycrystalline behavior. SEM micrographs showed the prepared powder was in the range 25–36 nm. SEM EDS mapping showed the presence of Fe and In ions in the Fe doped In 2O 3 sample. The highest remanence magnetization moment (6.624 × 10 −4 emu/g) is reached in the sample with x = 0.03.
