In-plane Anisotropy of the Magnetic Fluctuations in NaxCoO2-yH2O

C. Michioka, Y. Itoh, H. Ohta +2

We report the ${}^{59}$Co NMR studies of the in-plane anisotropy of bilayer hydrated Na${}_x\mathrm{Co}{\mathrm{O}}_2\cdot$$y{\mathrm{H}}_2\mathrm{O}$ using a oriented powder sample by a magnetic fie…
