Paper Abstract

Ti/Fe bilayers are deposited on SiO2 substrate in ultra-high- vacuum environment (10-9 Torr) in different sequence: SiO2/Fe(200 angstrom)/Ti(300 angstrom) and SiO2/Ti(300 angstrom)/Fe(200 angstrom). The interfaces of the films and their evolution at various annealing stages are studied by X-ray reflectivity measurements using high resolution triple-crystal X-ray diffractometer. The study shows that a different sequence of deposition results in different microstructure and affects subsequent evolution of the interfaces. It is also noticed that the annealed films are contaminated by the oxygen. Electron density profiles for the structures are obtained by nonlinear least square fits to the reflectivity curves.
