概要
- 論文の詳細を見る
Layered Co oxide Na_xCoO_<2・y>H_2O with the superconducting transition temperature T_c=4.5 K has been studied by <59>^Co-NMR. The Knight shift K estimated from the observed spectra of a powder sample exhibits almost temperature (T)-independent behavior above T_c and decreases with decreasing T below T_c. This result and the existence of the coherence peak in the spin-lattice relaxation rate versus T curve reported by the present authors indicate, naively speaking, that the singlet order parameter with s-wave symmetry is realized in Na_xCoO_<2・y>H_2O. Differences in the observed behaviors between the spectra of a nonaligned sample and those of an aligned sample embedded in epoxy adhesive by applying an external magnetic field are discussed.
