Abstract

We measured the low-temperature specific heat and de Haas-van Alphen oscillation in Sr₂RuO₄. The electronic specific heat C_e follows a T²-dependence below 0.7 K for the sample with a superconducting critical temperature T_c = 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.
