Zusammenfassung:
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.
