Abstract

Magnetic correlations in Ti-substituted Sr-3(Ru1-xTix)(2)O-7 have been studied by elastic and inelastic neutron-scattering 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, 0.24,0), which does not reflect the dominant magnetic instabilities in pure Sr3Ru2O7. Strong inelastic correlations near q(ic) were found to persist in Sr-3(Ru1-xTix)(2)O-7 far above the magnetic ordering; they become gapped in the ordered state.
