Abstract

We report a comprehensive study of magneto-oscillatory phenomena in the normal state of S $r_{2}$ Ru $O_{4}$ , the first layered perovskite superconductor $(T_{c} ≅ 1 K)$ not based on copper. The form of the quasiparticle spectrum observed may be interpreted in terms of an almost two-dimensional Fermi liquid model which is consistent with Luttinger's theorem and successfully predicts bulk thermodynamic and transport properties at low temperatures. A study of the spectra and transport along the c axis provides insights into the different normal state and superconducting behavior of S $r_{2}$ Ru $O_{4}$ and the cuprates.
