Abstract

Abstract We report the low temperature specific heat of single crystals of non-cuprate layered perovskite superconductor Sr 2RuO 4( T c ∼ 1K). In this paper we focus on the relation between the residual value γ 0 of the electronic specific heat and the specific-heat jump across T c. The results provide strong evidence for unconventional superconducting state.
