Abstrakt: Multilayers composed of 5×(6.4 nm Fe/5.6 nm Pt) were annealed at temperatures up to 735 °C. The intermixing was analyzed by analytical and high-resolution transmission electron microscopy. Intermixing and full ordering to the L10 structure was completed after annealing at 735 °C. The temperature dependence of intermixing is best described by a three-step process including diffusion through diluted alloys during initial intermixing (400–500 °C), diffusion through L12-ordered alloys (around 600 °C), and diffusion in the final L10-ordered film above 700 °C.
