【 摘 要 】
We calculated the nuclear spin-lattice relaxation rate 1/T-1 for the D-1+iD(2) superconducting state with impurities. We found that small amount of unitary impurities quickly produces the residual density of states inside the gap. As a result, the T-linear behavior in 1/T-1 is observed at low temperatures. Our results show that the D-1+iD(2) pairing symmetry of the superconducting state of Na0.35CoO2.yH(2)O is compatible with recent Co-59 1/T-1 experiments of several groups.【 授权许可】
