    Notes:
    Abstract With high-resolution (≈22 meV) angle-resolved photoemission spectroscopy, the Fermi surface of the first copper free layered-perovskite superconductor, Sr2RuO4, was determined. We observed three bands to cross the Fermi energy in qualitative agreement with LDA band structure calculations; one electron-like surface encircling the $$\overline \Gamma$$ point in the projected Brillouin zone, and two hole-like surfaces around the $$\overline X$$ point. The most striking aspect of the measurements is the observation of an extended van Hove singularity. It is located 17 meV below the Fermi energy and extends around the $$\overline M$$ point for about 0.2 Å−1 along both the $$\overline \Gamma$$ — $$\overline M$$ — $$\overline \Gamma$$ and the $$\overline X$$ — $$\overline M$$ — $$\overline X$$ directions.These observations demonstrate that van Hove singularities near the Fermi surface are a more generic feature of layered oxides, and call for a clarification of their exact role in oxide superconductivity.
