摘要

In the present paper, DC magnetization investigation on the insulating nanocrystalline powder samples of Ti_(1-x)Mn_xO_2 (x = 0,0.05,0.10, and 0.15) prepared by simple chemical route is reported. Structural measurements revealed phase pure anatase structure of TiO_2 when x < = 0.05 and a mixture of anatase and rutile TiO_2 along with the signature of Mn_3O_4 phase for x > = 0.05. Magnetic measurements exhibited the presence of ferromagnetic ordering at room temperature in samples having either small fraction of Mn or no Mn at all. This ferromagnetic signature is accompanied with paramagnetic contribution which is found to dominate with increase in Mn concentration.
