Abstract

We discuss magnetic excitations in several 214-ruthenates as observed by inelastic neutron scattering. In the spin-triplet superconductor Sr₂RuO₄ the magnetic excitation spectrum is dominated by incommensurate peaks arising from Fermi surface nesting. Evidence that Sr₂RuO₄ is close to the corresponding spin-density wave (SDW) ordering is found in the temperature dependence of the spectrum which shows some scaling behavior. The corresponding SDW ordering is finally induced by substituting a small amount of Ru through Ti. The possible role of ferromagnetic fluctuations is further analyzed on the base on Ca-substituted samples which exhibit a strongly enhanced macroscopic magnetic susceptibility.
