Magnetic correlations in Ti-substituted Sr 3 ͑Ru 1−x Ti x ͒ 2 O 7 have been studied by elastic and inelastic neutronscattering techniques. Below transition temperatures of the order of 20 K, the samples with 7.5 and 10% of Ti content exhibit an incommensurate spin-density wave ordering with a propagation vector q ic = ͑0.24, 0.24, 0͒, which does not reflect the dominant magnetic instabilities in pure Sr 3 Ru 2 O 7 . Strong inelastic correlations near q ic were found to persist in Sr 3 ͑Ru 1−x
