- 論文の詳細を見る
We report the measurements of the ^<29>Si Knight shift ^<29>K on the noncentrosymmetric heavy-fermion compound CePt_3Si in which antiferromagnetism (AFM) with T_N=2.2K coexists with superconductivity (SC) with T_c=0.75K. Its spin part ^<29>K_s, which is deduced to be K^c_s≥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_3Si.
