Abstract
We study the influence of defects on the structure of the order parame ter for a d(x2-y2) superconductor. Using a Ginzburg-Landau theory whic h couples the d-wave and s-wave components of the order parameter, we show that in the vicinity of defects there is an induced s-wave pairin g that extends up to a length scale given by the coherence length. We present results for columnar defects along different directions, twin boundaries, and point defects.
