Abstract

We give experimental evidence for an intrinsic magnetic moment in ZnO films prepared by pulsed laser deposition. In our study using magnetic measurements, we showed that we are able to tune the magnetic moment in ZnO by changing the oxygen content. We also observe that doping of 5 \% Co in ZnO does not introduce ferromagnetism. All of the arguments are supported by magnetotransport measurements, which reflect mainly the intrinsic properties of the film. It is contemplated in this study that the doping of Co in the ZnO matrix may in fact reduce the magnetic moment which is otherwise present in the pure ZnO.
