Abstract
We have used angle-resolved photoemission spectroscopy to determine the bulk electronic structure of Sr2RuO4 above and below the Fermi liquid crossover near 25 K. Our measurements indicate that the properties of the system are highly orbital dependent. The quasi-2D γ band displays Fermi liquid behavior while the remaining low energy bands show exotic properties consistent with quasi-1D behavior. In the Fermi liquid state below 25 K, the γ band dominates the electronic properties, while at higher temperatures the quasi-1D β and α bands become more important.
