Investigation of the Effect of cobalt doping on the magnetic properties of Co-Doped TiO2Prepared ViaSol-Gel Method

In this work, undoped and cobalt doped titanium dioxide nanoparticles in different molar ratio of 6, 12, 18 and 24, was prepared through the sol-gel method. We investigated the effect of cobalt doping on the magnetic properties of our samples.X-Ray diffraction (XRD) and scanning electron microscopy (SEM) results showed that the increase of cobalt doping produce a CoTiO3 phase and the particle sizes increase.Vibrating sample magnetometer (VSM) showed that cobalt doped TiO2 nanoparticles behaved paramagnetically and their magnetic susceptibilities enhanced of 0.7516×10-5 to 2.847×10-5 by increasing the doping level.
