SnO2 nano fibers and nanotubes were synthesized by electrospinning method. Magnetization measurement indicates that the SnO2 nano fibers and nanotubes annealed in air at 500 degrees C exhibit the room-temperature ferromagnetism and the ferromagnetism of nanotubes is stronger than the nano fibers. Selected area electron diffraction, X-ray diffraction and Raman measurements show that all the samples possess a typical rutile structure and no other impurity phases are observed. The results of the Raman spectra also indicate that there are lots of defects existing in the fabricated samples. The observed room-temperature ferromagnetism in SnO2 nano fibers and nanotubes possibly originates from oxygen vacancies. The field cooled (FC) and zero-field-cooled (ZFC) magnetization curves indicate that the Curie temperature T-C is above 300 K.
