摘要：
The magnetic fluctuation spectra are calculated for various phases of anisotropic superconductors. Both singlet and triplet superconducting phases can support anti-ferromagnetic fluctuations. For small values of the Coulomb repulsion, the spectra show power law frequency dependencies due to the nodes in the superconducting order parameter. For larger strengths of the Coulomb interaction, low energy critically damped collective excitations develop from the density of states in the gap. The q and dependence of the spectra can be used to deduce the character of the superconducting order parameter.
