| Abstract: | Ti1-xFexO2(x=0～0.050)diluted magnetic semiconductor nanoparticles were prepared by sol-gel method,and were annealed in Ar under 500℃.The crystal structure and the phase transition temperature of the nanoparticles were analyzed by thermogravimetry-differential thermal analysis(TG-DTA),X-ray diffraction(XRD) patterns and Raman spectroscopy.The magnetic properties of the nanoparticles were measured by vibrating sample magnetometer(VSM).The crystal structure of the Fe doped TiO2 sample is found to be anatase after annealing at 500℃.The grain size of the samples decreases with the increase of the Fe content.The magnetic properties of the samples show the obvious hysteresis in the central areas. |
