Abstract

The purpose of our research is to study the nuclear spin lattice relaxation rate of impure d-wave superconductors. We use the Green's function method to derive the approximation equation of density of states including the impurity scattering potential. We can get the analytic equation of the nuclear spin lattice relaxation rate that contained the impurity scattering potential in case of weak scattering potential and strong scattering potential in the simple form as the power series of Δ(T) and T. The numerical calculations show that there is coherence peak in the weak impurity scattering potential but there is no peak in the strong impurity scattering potential. Crown Copyright © 2009.
