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.
► Fe3+ doped In2O3 nanocubes are transferred from paramagnetic to super-paramagnetic by high magnetic field. ► Room temperature ferromagnetism of Ni2+ doped In2O3 nanocubes can be improved by high magnetic field treatments. ► The magnetic transitions or improvements are attributed to the rearrangement of doped ions in high magnetic fields.
