%X We show that local-moment screening in a Kondo lattice with d-wave superconducting conduction electrons is qualitatively different from the corresponding single Kondo impurity case. Despite the conduction-electron pseudogap, Kondo-lattice screening is stable if the gap amplitude obeys Delta < root TKD, in contrast to the singleimpurity condition Delta < T-K (where T-K is the Kondo temperature for Delta = 0 and D is the bandwidth). Our theory explains the heavy electron behavior in the d-wave superconductor Nd2-xCexCuO4.
