Abstract

We have measured the nuclear spin-lattice relaxation rate at the planar O site (1/T1)17O on the spin-triplet superconducting (SC) Sr2RuO4. It was found that the T dependence of (1/T1)17O in the zero field exhibits a small peak just below Tc, followed by the T-linear behavior. The T dependence of (1/T1)17O contrasts with the behavior of (1/T1)101Ru of the Ru site in the SC state, and based on a comparison of (1/T1)17O and (1/T1)101Ru, we suggest that some spin dynamics with low energy appear perpendicular to the RuO2 plane in the triplet SC state.
