Abstract
We studied the magnetic and the related electronic properties of Ni-doped rutile films (including oxygen deficiency ) prepared using a sol-gel method. A room-temperature ferromagnetism was observed in the : Ni films with the saturation magnetization () decreasing with increasing Ni doping and remaining constant above 6 at% Ni doping. The observed ferromagnetism below 6 at% Ni doping is interpreted as due to magnetic polaron formed by a trapped electron in oxygen vacancy and magnetic impurity ions around it. For small Ni doping, up to was obtained. The ferromagnetism for Ni doping above 6 at% is interpreted as due to the existence of Ni clusters that can explain the p-n conductivity transition observed by Hall effect measurements.
