“…In contrast to the interpretation in Ref. 13, the character of the magnetic ordering in Sr 3 ͑Ru 1−x Ti x ͒ 2 O 7 is not ferromagnetic but a spindensity wave close to the commensurate quarter-indexed order of up-up-down-down configuration, which has been reported for Mn-doped Sr 3 Ru 2 O 7 .…”

“…This maximum is rapidly suppressed by the Ti doping. 13 Furthermore, the signature of the metamagnetic transition in the magnetization versus magnetic field curves disappears for a Ti content of 4% in the crystals studied in Ref. 13 as well as in our crystals.…”

“…Nevertheless the small Ti contents significantly alter the resistivity. For Ti concentrations between 0% and 4% the re- sistivity decreases when cooling from 10 to 0.5 K, whereas it increases for contents larger than 5%, 13 suggesting the critical concentration to be around x cr−Ti Ӎ 4%.…”

“…In the case of Sr 3 Ru 2 O 7 , it has recently been demonstrated that doping with Ti or Mn on the Ru site induces interesting effects. 12,13 By only a few percent of Mn substitution, the ground state of Sr 3 Ru 2 O 7 becomes an antiferromagnetic insulator with the magnetic ordering described by a commensurate ͑0.25,0.25,0͒ propagation vector. 12 For Tisubstituted Sr 3 Ru 2 O 7 , Hooper et al 13 reported the suppression of the metamagnetic transition and the upturn of the low-temperature specific heat for low Ti content.…”

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 Ti x ͒ 2 O 7 far above the magnetic ordering; they become gapped in the ordered state.

“…[11][12][13] The negative Weiss temperature of Sr 3 Ru 2 O 7 suggests that AFM correlations dominate its magnetic ground state; this point of view has been confirmed in neutron scattering and nuclear magnetic resonance measurements. 11,12 The decrease in negative Weiss temperature for ͑Sr 0.9 Ca 0.1 ͒ 3 Ru 2 O 7 suggests that the Ca substitution for Sr suppresses the AFM correlations.…”

We have studied the structural, magnetic, and electronic transport properties of (Sr0.9Ca0.1)3Ru2O7 using single crystals grown by a floating-zone technique. The structure analysis by Rietveld refinements reveals that the Ca substitution for Sr intensifies the structure distortion; the rotation angle of the RuO6 octahedron increases. This structure change tunes magnetic and transport properties dramatically. The magnetic ground state switches from an itinerant metamagnetic state for Sr3Ru2O7 to a nearly ferromagnetic state for (Sr0.9Ca0.1)3Ru2O7. The Fermi liquid behavior occurs in Sr3Ru2O7, but is suppressed in (Sr0.9Ca0.1)3Ru2O7. These results strongly suggest that lattice, spin, and charge degrees of freedom are strongly coupled in this system. The band width narrowing caused by the structure distortion should be responsible for the enhancement of ferromagnetic correlations and the change of transport properties.

We review our recent work concerning the search for the superconducting state realised in Sr 2 RuO 4 . The orbital symmetry of the order parameter in this spin triplet superconductor is widely believed to be chiral one with d-vector along the crystal c-axis. The three band, three dimensional model with two different phenomenological interaction parameters is able to explain most of the existing data in quantitative way. This is also true for the recently observed "rotation" of the d-vector in magnetic field directed along c-axis.
