Abstract:
We report detailed normal state measurements of the resistivity,
magnetic susceptibility and specific heat of high-quality single
crystals of Sr2RUO4, the only copper-free, layered perovskite
superconductor (T-c approximate to 1K). It is intriguing that despite
its very strong anisotropy (the ratio of the interlayer to in-plane
resistivity exceeds 500) arising from the essentially two-dimensional
Fermi surface, the normal state properties are consistent with a
universal description for a the investigation of the limits of
applicability of Fermi liquid theory to other highly correlated layered
compounds, including high-T-c cuprates.
