摘要：

The charge-ordered state in a quasi-two-dimensional organic superconductor ss"-(BEDT-TTF)(4)[(H3O)Ga(C2O4) 3]center dot C6H5NO2 has been investigated using C-13 NMR spectroscopy in a high magnetic field. Enhanced resolution of the high-field spectrum allows us to estimate the site charges in the low-temperature charge-ordered state below 8.5 K. The observed strong increase in the charge imbalance suggests that superconductivity appears on the electronic state with a strong charge modulation. From the NMR intensity ratio of signals from the charge-rich and charge-poor sites, we discuss a possible charge pattern with threefold modulation, which could be stabilized by the effects of electron-electron correlations.
