抄録

Although angle-resolved photoemission spectroscopy (ARPES) has been used for detailed study of the layered perovskite copper-oxide superconductors for nearly ten years, Sr₂RuO₄ is the first metal of this structural class for which it has been possible to obtain detailed Fermi surface data from both quantum oscillations and ARPES. We show that the two techniques give very different results, and present strong evidence that the current interpretation of ARPES data is not representative of the bulk electronic structure of Sr₂RuO₄.
