Abstract
We present harmonic generation measurements of the intrinsic nonlinear current density j2 of (YBCO) films at temperatures close the Tc. Experiments on a range of different quality samples allow us to extract the dependence of j2 on the penetration depth of the superconductor. In order to model these results, we calculate the intrinsic nonlinear current response of d-wave superconductors in the Meissner regime in the presence of nonmagnetic impurities within the selfconsistent T-matrix approximation.Citation
