Nuclear spin-lattice relaxation rate in the D+iD superconducting state: implications for CoO superconductor

Abstract

We calculated the nuclear spin-lattice relaxation rate 1/T1 for the D+iD 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/T1 is observed at low temperatures. Our results show that the D+iD pairing symmetry of the superconducting state of Na0.35CoO2 · yH2 O is compatible with recent 59Co 1/T1 experiments of several groups.
