Abstract

We have measured ¹⁷O-nuclear spin-lattice relaxation rate T₁^-1 in the superconducting state of Sr₂ RuO₄. A large enhancement of T₁^-1 was observed in the mixed state, affected by the thermally enhanced fluctuation of vortices. T₁ has two major components well below T_c: a shorter-T₁ component comes from the oxygen sites close to the vortices, whereas a longer-T₁ component is from the sites far from the vortices. A peak of (T₁ T)^-1 appears when the thermal fluctuation rate τ^-1 become comparable to the NMR frequency.
