TL;DR: In this article, an organic Mott insulator, β'-(BEDT-TTF) 2 ICl 2, is metallized by application of extremely high pressure up to 9.0GPa.
Abstract: An organic Mott insulator, β'-(BEDT-TTF) 2 ICl 2 , is metallized by application of extremely high pressure up to 9.0GPa. When the metallic state is stabilized, superconductivity with the highest transition-temperature (T c ) among organic systems appears. The maximum T c that we observed was 14.2K(onset) at 8.2GPa. A magnetic-field effect on this superconductivity and normal-state properties are discussed in terms of comparison with other organic superconductors.

TL;DR: In this article, the authors characterize paramagnetic Mott insulators by their response to static, non-magnetic impurities, and argue that a number of recent experiments favor spinon confinement in the reference mott insulating state.
Abstract: We characterize paramagnetic Mott insulators by their response to static, non-magnetic impurities. States with spinon deconfinement (or spin-charge separation) are distinguished from those with spinon confinement by distinct impurity susceptibilities and finite-size spectra. We discuss the evolution of physical properties upon doping to a d-wave superconductor, and argue that a number of recent experiments favor spinon confinement in the reference Mott insulating state.

TL;DR: The magnetism of deuterated κ-(BEDT-TTF)2Cu[N(CN)2]Br was investigated by magnetization and muon spin rotation (μSR) measurements.
Abstract: The magnetism of deuterated κ-(BEDT-TTF)2Cu[N(CN)2]Br, which was situated in the vicinity of a superconductor–antiferromagnet phase boundary, was investigated by magnetization and muon spin rotation (μSR) measurements. Magnetic ordering was observed by μSR measurement under the zero-field condition. Internal fields at muon sites were lower than those of κ-(BEDT-TTF)2Cu[N(CN)2]Cl. The magnetic transition temperature TN was found to be increased by applying a magnetic field in the magnetization measurements. These two measurements enabled us to conclude that TN at zero field was 11.8 ± 0.7 K, which was significantly lower than the value reported in NMR studies (14–15 K). This finding suggests that this material undergoes Neel order and Mott transition at very close but separated temperatures.
