在氧气氛下，采用射频偏压溅射法制备了Fe-O衬底，在衬底上沉积了不同氧化时间的L10 FePt薄膜。在1 nm厚的Fe-O衬底上制备的FePt薄膜经高温退火后，获得了非常好的（001）织构和完美的垂直磁化强度。（001）织构的演变伴随着fcc到fct的相变，两者都是由再结晶过程驱动的。Fe-O底层不仅作为模板，而且在退火过程中提供应力以帮助原子迁移。
L10 FePt thin films were deposited on an Fe-O underlayer prepared by RF bias sputtering in an oxygen atmosphere for different oxidization time. Very good (001) texture and perfect perpendicular magnetization were obtained in the FePt film on 1-nm-thick Fe-O underlayer after high temperature annealing. The (001) texture evolution was accompanied by fcc-to-fct phase transformation, and both were driven by a recrystallization process. The Fe-O underlayer not only acts as a template, but also provides a stress to help the atom migration during annealing.
