Abstract

We have studied the effect of spin fluctuations on select properties of high-Tc superconductors with the pairing mechanism left largely unspecified. The specific-heat jump at Tc and its slope are calculated for various characteristic spin-fluctuation spectra. The zero-temperature gap edge and second critical magnetic field are also considered. Results specific to a marginal Fermi-liquid model are presented. Finally we consider the effect of spin fluctuations on the isotope effect.
