摘　　要：Fe/Sn-codoped In_(2)O_(3)powders and films are prepared by a vacuum annealing process and a pulsed laser deposition technique,respectively.The structural and magnetic properties of the samples are investigated.The obvious room-temperature ferromagnetism is observed in both(In_(0.92)Fe_(0.05)Sn_(0.03))_(2)O_(3)powders and films,but their magnetic behaviors are very different.The ferromagnetism of the vacuum-annealed powders is partially due to precipitated Fe_(3)O_(4)impurity.By contrast,the ferromagnetism of the films is intrinsic and does not originate from any magnetic impurity,as confirmed by the extensive x-ray absorption spectroscopy and magnetization studies.
