Abstract

We measured the low-temperature specific heat and de Haas-van Alphen oscillation in Sr2RuO4. The electronic specific heat Ce follows a T2-dependence below 0.7 K for the sample with a superconducting critical temperature Tc = 1.52 K, suggesting line nodes in the superconducting gap. Three kinds of cylindrical Fermi surfaces were discussed from a view point of their cyclotron effective masses.
