RESUMO
We study the dynamical spin susceptibility, chi(q,omega), in the normal and superconducting states of Sr(2)RuO(4). In the normal state, we find a peak in the vicinity of Q(i) approximately (0.72 pi,0.72 pi) in agreement with recent inelastic neutron scattering experiments. We predict that for spin triplet pairing in the superconducting state a resonance peak appears in the out-of-plane component of chi, but is absent in the in-plane component. In contrast, no resonance peak is expected for spin singlet pairing.
