Paper Abstract

We have included in our two-gap model of superconductivity in the cuprates the effect of pair breaking caused by magnetic impurity scattering. This model explains many of the observed features of the cuprates including the temperature and frequency dependence of the surface resistance and penetration depth, the anomalous temperature dependence of the upper critical magnetic field, and the zero bias anomalies observed between cuprates and normal metal contacts. This model can also explain many of the phase coherence experiments in YBaCuO on the basis of magnetic scattering at an interface or grain boundary due to strain-induced oxygen loss. We have recently extended this model to calculate the electromagnetic properties and the density of states in the presence of magnetic scattering. The latter results will be presented here.
