Abstract

We report ⁹⁹Ru Knight-shift (⁹⁹K) measurement on the high-quality Sr₂RuO₄ with a superconducting transition temperature T_c∼ 1.5 K. Its spin component, ⁹⁹K^s due to the core polarization effect caused by Ru-4d spins, is nearly one order of magnitude larger than that of the ¹⁷O Knight shift (¹⁷K^s). The 4d-spin susceptibility that has been more precisely measured from ⁹⁹K^s than ¹⁷K^s shows no change across T_c at all. The present result reinforces that Sr₂RuO₄ is the spin-triplet p-wave superconductor in which electrons are bound together in parallel-spin pairs parallel to the RuO₂ plane.
