Description
The field-swept nuclear magnetic resonance (NMR) spectra of 59Co in the superconductor Na0.35CoO2.1.3H2O have been measured at several magnetic fields below Tc. The anisotropic Knight shift Ky seems to decrease with decreasing temperature without broadening of the spectrum, indicating either the site-selective diamagnetic effect, which may result in the spin-triplet superconductivity, or the decrease of the intrinsic spin shift. Analysis of the magnetic field dependence of the Knight shift at 2K revealed that the superconductivity occurs in an unconventional way
