为了在Fe-Ta-C磁性软衬层（SUL）上形成FePt（001）织构，在SUL和FePt/MgO层压记录层之间使用组合的SiO2/MgO中间层。非晶SiO2层的功能是切断SUL和记录层之间的外延生长关系，并建立MgO（200）织构。薄的FePt层外延生长在MgO层上，并在退火后转变为（001）织构的L10 FePt膜。将Fe-Ta-C SUL的表面粗糙度从0.74 nm增加到2.35 nm对FePt（001）织构没有显著影响，但对FePt晶粒c轴分散和FePt L10相有序性有影响。
In order to develop the FePt (001) texture on an Fe–Ta–C magnetic soft underlayer (SUL), a combined SiO2/MgO intermediate layer is used between the SUL and FePt/MgO laminated recording layer. The function of the amorphous SiO2 layer is to cut the epitaxial growth relationship between the SUL and recording layer and to establish the MgO (200) texture. The thin FePt layers are epitaxially grown on the MgO layers and transformed into (001)-textured L10 FePt films upon annealing. Increasing the surface roughness of the Fe–Ta–C SUL from 0.74 to 2.35 nm does not significantly affect the FePt (001) texture, but has an effect on the FePt grain c-axis dispersion and the FePt L10 phase ordering.
