Abstract

We have calculated the effect of impurity scattering on the temperature dependence of the nuclear-spin-lattice-relaxation rate and Knight shift for a two-dimensional superconductor with dx2-y2 symmetry. Lowest-order Born scattering as well as T-matrix scattering in the unitary limit is considered. Strong scattering profoundly changes the low-temperature dependences of both quantities giving rise to a constant contribution. Strong-coupling effects, which are never large, are included approximately in our simplified Eliashberg formulation of the problem.
