| L10 ordered FePt alloys are the candidate materials for the next generation ultrahigh area density magnetic recording, due to their large magnetocrystalline anisotropy constant. How to prepare FePt films with L10 ordered phase has become a recent focus. In this review, the preparative methods for L10 FePt films, including the selection of proper base materials, the layer-by-layer deposition, the embedding of underlayer or intermediate layer, the addition of alloying elements or a third additive, are briefly introduced. The feature and disadvantage of these methods are discussed, and the future development of FePt films is prospected. |
