Abstract

We report the results of a study of the in-plane and out-of-plane resistivity of the layered perovskite superconductor Sr2RuO4 at temperatures between 4 and 1300 K. Although the material is a very good metal at low temperatures, with in-plane mean free paths (l) of thousands of lattice spacings, l falls smoothly to less than 1 Angstrom at 1300 K with no sign of resistivity saturation at the Mott-Ioffe-Regel limit. Measurements of the incoherent out-of-plane resistivity over the same range of temperature are also discussed. [S0163-1829(98)50840-5].
