    The surface band structure of the (1×1) and the pseudohexagonally reconstructed phases of Pt{100} have been mapped using angle-resolved photoemission. The experimentally determined surface band structure for the metastable (1×1) phase agrees well with the calculated one. The surface Fermi surface for the (1×1) phase consists of well-nested electron-hole pockets centered around the X̄ and M̄ points. Upon reconstruction these disappear and electron-hole surfaces centered around the X̄ and M̄ points are created 0.2 eV below the Fermi edge. These observations suggest that the (1×1) phase may be unstable with respect to the formation of spin-density waves. © 1995 The American Physical Society.
