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.
