Nuclear magnetic relaxation rate in a noncentrosymmetric superconductor
Nuclear magnetic relaxation rate in a noncentrosymmetric superconductor
For a noncentrosymmetric superconductor such as CePt3Si, we consider a Cooper pairing model with a two-component order parameter composed of spin-singlet and spin-triplet pairing components. We demonstrate that such a model on a qualitative level accounts for experimentally observed features of the temperature dependence of the nuclear spin-lattice relaxation rate …
