The compositional analysis done on the synthesized undoped and cobalt (Co)-doped titanium dioxide ( TiO<sub>2</sub>) nanoparticles by X-ray photoelectron spectroscopy and energy dispersive X-ray analysis suggests oxygen deficiency in undoped and Co-doped TiO<sub>2</sub> samples. Magnetic investigations by vibrating sample magnetometer (VSM) indicate that(More)
Undoped and Mn-doped cobalt ferrite (CoFe<sub>2</sub>O<sub>4</sub>) nanoparticles were synthesized and characterized for thermal conductivity and magnetic properties. Room temperature ferromagnetism and an increase in saturation magnetization due to Mn doping (65.4 emu/g for 3 at.% of Mn and 20.8 emu/g for undoped CoFe<sub>2</sub>O<sub>4</sub>(More)
