Abstract
Results from a LEED analysis of NiAl(110) demonstrate that it possesses a large rippled relaxation away from its hypothetical truncated bulk surface, with the Al sites of the top composite Ni-Al layer being displaced approximately 0.22 Å above the Ni sites. The evidence for this rippling is strong, since the agreement achieved between calculated and experimental profiles is of the same quality obtained in better LEED analyses of monatomic surfaces.
