The spinel-structure CuIr _2 S _4 compound displays a rather unusual orbitally-driven three-dimensional Peierls-like insulator–metal transition. The low- T symmetry-broken insulating state is especially interesting due to the existence of a metasta

The spinel CuIr 2 S 4 exhibits a temperature-induced metal–insulator (M–I) transition at around T M−I =226 K with a structural transformation, at which a simultaneous bond dimerization with spin-singlet state and charge-ordering transition take

Publikováno v: Hyperfine Interactions. 159(1-4):181-185

We have investigated the metal-insulator transition (MIT) of CuIr2S4 by a high resolution NMR measurement. The Cu-NMR spectrum below T MI is broadened and split into four Cu signals with sizable electric quadrupole interactions. The NMR results are c
