摘要：
Impurity scattering will provide a crucial test for d-wave superconductor in high Tc copper-oxides. Among other things we calculate the static spin susceptibility and find a simple relation between the susceptibility and superfluid density s(T)=[(0)/(T)]2 is broken in the presence of impurity scattering. Also we generalize Lees universal conductivity at T=0 K. In the presence of a finite concentration of impurity, the order parameter 00 in the conductivity has to be replaced by (,0) and (,0) is accessible through the tunneling experiment of the density of states. © 1995 The American Physical Society.
