- W2797146749 abstract "Mn-doped TiO2 (Mn= 1%, 2% and 3%) nanoparticles prepared by simple and cost effective sol-gel technique and calcined at 500 °C. The sample with dopant concentration, 1% and 2%, exhibits mixed anatase and rutile phase, where as sample with dopant concentration, 3% show pure anatase phase. Here we have studied the effect of doping concentration and temperature on the magnetic properties of the synthesized samples. The magnetization verses temperature results gives indication of some transition at temperature around 2-40 k. Further we proceed with magnetic field versus magnetization, it is found that at 2 K all the samples behaves as ferromagnetic material. However, at 30K, the synthesized samples are completely behaves like paramagnetic material. Origin for ferromagnetism is attributed to the presence of oxygen vacancies or due to doping of Mn in TiO2.Mn-doped TiO2 (Mn= 1%, 2% and 3%) nanoparticles prepared by simple and cost effective sol-gel technique and calcined at 500 °C.
