摘要：
Fe3+ and Ni2+ (5 at.%) doped In2O3 single-crystalline nanocubes showed distinctly different magnetic properties before and after 4T high magnetic field treatments. Fe3+ doped In2O3 nanocrystals were transferred from paramagnetic to super-paramagnetic by treating them in high magnetic field while Ni2+ doped In2O3 nanocubes obviously improved primary ferromagnetism. These special phenomena may open up a way to endow nanomaterials with novel and special functions. In addition, their magnetic properties were not caused by impurities or changes of morphologies and crystalline structures. (C) 2011 Elsevier Ltd. All rights reserved.
