Popis:	Mn-doped TiO2 nanorods which showed room temperature ferromagnetic (RTFM) behavior have been synthesized by a hydrothermal method. Analysis of X-ray diffraction and Raman spectral data reveal the formation of anatase phase without any impurity phase. From the hysteresis loop measurements, it is possible to estimate the two parameters, magnetization (MS) and coercivity (HC) which are 33 memu/g and 89 Oe respectively, for 5 at% Mn-doped TiO2. The two parameters (MS, HC) are strongly dependent on the Mn doping concentration. The origin of the RTFM is understood in terms of the concentration of oxygen vacancies and/or defects which is created by Mn doping.
