NMR study on the metal–insulator transition of CuIr2S4

We have investigated the metal-insulator transition of CuIr2S4 using high resolution NMR measurements. The Cu-NMR spectra below TMI are broadened and split into four Cu signals with nuclear quadrupole interactions, confirming the existence of charge ordering of Ir+3 and Ir4+ and the spin dimerizatio...

Summary:We have investigated the metal-insulator transition of CuIr2S4 using high resolution NMR measurements. The Cu-NMR spectra below TMI are broadened and split into four Cu signals with nuclear quadrupole interactions, confirming the existence of charge ordering of Ir+3 and Ir4+ and the spin dimerization of Ir4+ spins, as revealed by a recent X- ray study.
