Abstract
We report 99Ru Knight-shift (99K) measurement on the high-quality Sr2RuO4 with a superconducting transition temperature Tc∼ 1.5 K. Its spin component, 99Ks 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 (17Ks). The 4d-spin susceptibility that has been more precisely measured from 99Ks than 17Ks shows no change across Tc 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.
