Abstract
The impact of annealing at 300 °C on the elemental composition and the atomic structure of the Co/V interface in the 2.5 Ã
Co/70Â Ã
V/MgO (100) system has been investigated by medium energy ion scattering (MEIS) using 100 keV He+ ions. By combining the experimental MEIS results with simulations we show that, while the Co/V interface is abrupt for the system kept at room temperature, annealing at 300 °C induces a strong interdiffusion leading to a Co0.5V0.5 surface bcc alloy with a high degree of disorder. Additionally, the MEIS data suggest that the surface of the annealed system is slightly rumpled by ~ 0.2 Ã
