Title: Mixture of ordered domains in the NiAl(111) surface

Abstract

The atomic structure of the NiAl(111) surface has been investigated through a LEED I-V analysis. In order to achieve a unique, consistent agreement between experimental and calculated I-V spectra, this surface is determined to be a 50-50 mixture of two ordered domains, one of which is Al terminated and the other is Ni terminated. The relaxations of the outermost interlayer spacings in each domain have been determined as well, and they are different for the two domains. The NiAl(111) surface is the first reported example of a binary-alloy surface in which a mixture of ordered domains with differing terminations coexists.
