    Notizen: Abstract We have investigated the normal-state conduction of superconducting Sr2RuO4 (Tc ∼ 1K), which is isostructural to La2−xSrxCuO4. The resistivity of single crystals shows a crossover at TM∼130K from 3D metallic conduction at lower temperatures to 2D one at higher temperatures. Concerning the temperature dependence of the out-of-plane resistivity, we present a systematic interpretation based on competition between the life time of the quasiparticles and the time for the quasiparticles to travel between the adjacent RuO2 planes.

    Normal-state and superconducting properties of Sr2RuO4 (1996)
    Springer

    Thema: Physik
    Notizen: Abstract We discuss some of the current issues on the copper-free layered perovskite superconductor Sr2RuO4, for which a sharp transition at Tc = 1.2 K has been reproducibly obtained. The normal state is characterized as an essentially twodimensional Fermi liquid, and the coherent interlayer transport is established only at low temperatures. The cylindrical Fermi surface observed by de Haas-van Alphen experiments is consistent with other thermodynamic and transport properties. Although the specific heat jump across Tcconfirms the bulk superconductivity, the large residual T-linear term which correlates with the variation in Tcis unusual and suggestive of unconventional pairing.
