Abstract
In this work TiO2 nanoparticles and nanorods have been synthesized and their structural properties have been investigated in different preparation conditions The effect of cobalt doping in different molar ratios of 6 12 18 and 24 on physical properties of nanoparticles was studied Undoped and cobalt doped titanium dioxide nanoparticles was prepared through the sol–gel method Nanostructures were characterized by using Xray diffraction and scanning electron microscopy techniques The effect of cobalt doping on the magnetic properties is also investigated by vibrating sample magnetometer It confirmed that cobalt doped TiO2 nanoparticles show paramagnetic behavior and their magnetic susceptibilities enhanced by increasing the doping level Results show that increasing of cobalt doping produce a CoTiO3 phase and the particle sizes increase
