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 T_c, 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.
