Abstract

Inelastic-neutron-scattering measurements have been performed on single crystals of the spin-triplet superconductor Sr2RuO4. Incommensurate spin fluctuations were observed in both the normal and superconducting phases with the same intensity below and above Tc. Measurements of the wave-vector dependence of the magnetic scattering along the c axis suggest an itinerant character of the Ru form factor and an isotropic susceptibility.
