摘要：
Fe doped In2O3 nanocrystals were synthesized by a coprecipitation method under external magnetic fields. X-ray diffraction data and high-resolution transmission electron microscopy analyses indicated the formation of single phase without any parasitic phases. The crystal structure of the nanocrystals is tuned by changing Fe concentrations and intensities of magnetic fields. Room temperature ferromagnetism in Fe doped In2O3 nanocrystals can be activated by suitable magnetic fields. (c) 2007 American Institute of Physics.
