Abstract: Dilute Magnetic Semiconductor (DMS) has been the focus of many studies recently as it has potential applications in the fields of microelectronics, spintronics, optoelectronics etc. due to its unique structural and magnetic spin properties. In the thesis, the formation and characteristics of DMS thin films have been investigated. Three main systems have been studied; Co-doped TiO2, Co-doped ZnO and Cu-doped ZnO. Doping cobalt is the conservative principle where most of the researchers are doping magnetic elements into DMS to create magnetism. However, doping of copper, a non-magnetic element is to prove that the intrinsic magnetic property is created from the spin-spin interaction in the thin film but not from the small magnetic cluster formation. Clusters of copper and secondary phases of coppers are non-magnetic.
