57Fe and 119Sn CEMS Study of SnO2 Films Implanted with 57Fe

The origin of magnetic interactions in Diluted Magnetic Semiconductors (DMS) is attracting a great attention as a basic problem on magnetism[1-2]. This subject is still an issue of controversy. In all of these works, the observed ferromagnetism has been attributed to interactions between the magnetic impurities, but the main source has never been associated to magnetically ordered defects. We have reported the different types of magnetic source in case of Fe doped SnO2 powder [3], and the phonon density of states of rutile type structures [4]. Defects in DMS can also contribute to saturation magnetization. Here we have made the thin films of SnO2 implanted with 57Fe and characterized them by 57Fe and 119Sn conversion electron Mössbauer spectrometry (CEMS).
