Abstract

TiO₂ nanotubes with a diameter around ∼ 550 nm have been prepared by electrospinning method. The synthesized nanotubes were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Raman spectroscopy and superconducting quantum interference device (SQUID). The XRD and Raman results indicate that TiO₂ nanotubes have mixed of anatase and rutile structure. Magnetization measurements indicate that TiO₂ nanotubes exhibit room temperature ferromagnetism with remanent magnetization (M_r) and coercivity (H_C) of about 46 Oe and 0.0018 emu/g, respectively, which may results due to the presence of defects in the TiO₂ nanotubes. The field cooled (FC) and zero field cooled (ZFC) magnetization curves indicate that there is no contamination of ferromagnetic cluster and the Curie temperature T_C is above 350 K.
