Charge disproportionation in the spin-liquid candidate κ-(ET)_{2}Cu_{2}(CN)_{3} at 6 K revealed by ^{63}Cu NQR measurements
The spin-liquid candidate κ-(ET)_{2}Cu_{2}(CN)_{3} [ET: bis(ethylenedithio)tetrathiafulvalene] does not exhibit magnetic ordering down to a very low temperature, but shows a mysterious anomaly at 6 K. The origin of the so-called 6-K anomaly is still under debate. We carried out nuclear quadrupole re...
