Abstract
High resolution medium energy ion scattering has been used to study the interlayer spacing and atomic vibrations at the Ni(111) surface in the temperature range of 430-1100 K. The surface was not found to exhibit significant relaxation; it remains nearly bulk-terminated for all temperatures studied. The amplitudes of the atomic vibrations at T < 800 K are enhanced by 30-40% with respect to their bulk values. This enhancement increases drastically at higher temperatures, so that the surface amplitudes become twice as large as the bulk amplitudes at 1100 K. We did not observe changes in the surface-structural properties near the Curie point.
