Evidence for incommensurate spin fluctuations in Sr2RuO4

We report inelastic neutron scattering measurements in the normal state of SnRuO4 reveal the existence of significant incommensurate magnetic spin flu ctuations located at q(o) = (+/-0.6 pi/a, +/-0.6 pi/a, 0). This finding con firms recent band-structure calculations that have predicted incommensurate magnetic responses related to dynamical nesting properties of its Fermi su rface and points towards the possibility of a competition between p-wave sp in triplet and d-wave spin singlet superconductivity in Sr2RuO4 We present a comparison between low energy spin fluctuations, converted in absolute un its, from inelastic neutron scattering measurements and previous nuclear ma gnetic resonance studies.
