当沉积速率低于0.6Å/s时，溅射沉积Fe薄膜表现出（100）择优取向。在较低的沉积速率条件下获得了（100）取向的铁层，并在其上沉积了（100）取向的Pt层。在600℃氢气中退火后，直接沉积在玻璃盘基底上的Fe(100)/Pt（100）双层薄膜，没有任何种子层，表现出具有（001）择优取向的FePt高有序FCT合金相。Fe[3nm]/Pt[3nm]双层薄膜经退火处理后，垂直方向的方形比和矫顽力分别为1.0和4.8kOe。
Sputter-deposited Fe thin films exhibited (100) preferential orientation when they were deposited at a lower deposition rate below 0.6Å/s. The (100)-oriented Fe layer attained at a lower deposition rate condition induced (100) orientation of Pt layers deposited on it. Fe(100)/Pt(100) thin bilayered films deposited directly on glass disk substrates, without any seed layers, exhibited FePt highly ordered FCT alloy phase with (001) preferential orientation after annealing at 600°C in hydrogen atmosphere. Fe[3nm]/Pt[3nm] thin bilayered films exhibited squareness ratio and coercivity in perpendicular direction of 1.0 and 4.8kOe, respectively, after the annealing process.
