摘要：

We measured the low-temperature specific heat and de Haas-van Alphen oscillation in Sr2RuO4. The electronic specific heat C-c follows a T-2-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. (C) 2000 Elsevier Science B.V. All rights reserved.
