Medium energy ion scattering has been used to examine the interlayer spacings and surface vibrations at the Ni(111) surface at 300-1100 K. We find that the surface layers, which are known to have a bulk terminated structure at 300 K, do not exhibit a significant (> 2%) interlayer relaxation (with respect to the bulk) in the temperature range in question. Monte Carlo simulations of the angular spectra show that the amplitudes of surface vibrations are larger than the bulk values by ∼ 30-40%. No anomalies in the vibrations and interlayer spacing near the Curie point have been observed. On the other hand, carbon dissolution into the bulk was seen near Tc for slightly contaminated surfaces.
