摘要：

Implantation of O ions into Fe/Co/Fe thin film has been performed to modify its structural and magnetic properties. X-ray reflectivity and atomic force microscopy measurements indicate that after implantation, interface and surface roughnesses have been increased. X-ray reflectivity measurement of the implanted sample at higher fluence shows intermixing at the interface of Fe/Co and Co/Fe layer. 1x10(16) ions/cm(2) O-ions reduces the coercivity of film from 50 Oe to 31 Oe. After 5x10(16) ions/cm(2) O ion fluence, film exhibits two fold magnetic anisotropy and the magnetic moment of the film has been increased. Ion implantation induces broadening in the Mossbauer spectrum suggest that the FeCoO and FeCo component at the interface have been formed, which enhances the magnetic moment of the film.
