Evidence for Novel Pairing State in Noncentrosymmetric Superconductor CePt3Si: 29Si-NMR Knight Shift Study

We report the measurements of the 29 Si Knight shift 29 K on the noncentrosymmetric heavy-fermion compound CePt 3 Si in which antiferromagnetism (AFM) with T N =2.2 K coexists with superconductivity (SC) with T c =0.75 K. Its spin part 29 K s , which is deduced to be K s c ≥0.11 and 0.16% at respective magnetic fields H =2.0061 and 0.8671 T, does not decrease across the superconducting transition temperature T c for the field along the c -axis. The temperature dependence of nuclear spin–lattice relaxation of 195 Pt below T c has been accounted for by a Cooper pairing model with a two-component order parameter composed of spin-singlet and spin-triplet pairing components. From this result, it is shown that the Knight-shift data are consistent with the occurrence of the two-component order parameter for CePt 3 Si.We report the measurements of the
