Structural, Optical and Magnetic Properties of α-Fe2O3 Nanoparticles

摘要: High purity Iron oxide (α-Fe2O3) powder was grinded for 16 hours using mechanical milling and studied its physical properties. The micro structures, crystallite size of the nanoparticles were examined X-ray diffractrometer (XRD). From this it found that particles in rhombohedral structure with average 39 nm. optical absorbance reflectance spectra recorded UV–Vis-NIR spectrophotometer wavelength range 200 – 2500 band gap as 2.08 eV. magnetic measurements carried out vibrating sample magnetometer at 100 K. studies moment increased increase applied field saturation not observed even high fields.
