Abstract
Subject headings
Close
- Driven by reconstruction and relaxation, by the appearance of surface electron states and resonances, the surface properties and related temperature scales of strongly correlated f-materials may differ dramatically from those in the bulk. Applying low energy electron and photoelectron diffraction techniques, momentum-resolved photoelectron spectroscopy and ab initio calculations, we demonstrate that the In-terminated surface of the heavyfermion superconductor CeIrIn5 experiences a reconstruction with a (root 2v x root 2)R45 degrees ordered structure. The latter appears due to the displacement of In atoms with respect to the Ir sublattice. We show that the electronic structure and related properties of the reconstructed In surface differ remarkably from the unreconstructed case. Namely, the predicted surface states with Rashba-type spin splitting do not appear. Our results suggest surface instabilities in similar quasi-two-dimensional strongly correlated f-materials, for which surface reconstructions can be unveiled by means of diffraction techniques.
