Phys. Rev. Lett. 85, 5194–5197 (2000)Fermi Surface, Surface States, and Surface Reconstruction in Sr2RuO4Received 2 May 2000; published in the issue dated 11 December 2000 The electronic structure of Sr2RuO4 is investigated by high angular resolution ARPES at several incident photon energies. We address the controversial issues of the Fermi surface (FS) topology and the van Hove singularity at the M point, showing that a surface state and the replica of the primary FS due to √2×√2 surface reconstruction are responsible for previous conflicting interpretations. The FS thus determined by ARPES is consistent with the de Haas–van Alphen results, and it provides additional information on the detailed shape of the α, β, and γ sheets. © 2000 The American Physical Society URL:
