Iridium-based 5d transition-metal oxides are attractive candidates for thestudy of correlated electronic states due to the interplay of enhancedcrystal-field, Coulomb and spin-orbit interaction energies. At ambientpressure, these conditions promote a novel Jeff = 1/2 Mott insulating state,characterized by a gap of the order of ~0.1 eV. We present high-pressureelectrical resistivity measurements of single crystals of Sr2IrO4 and Sr3Ir2O7.While no indications of a pressure-induced metallic state up to 55 GPa werefound in Sr2IrO4, a strong decrease of the gap energy and of the resistance ofSr3Ir2O7 between ambient pressure and 104 GPa confirm that this compound is inthe proximity of a metal-insulator transition.

Persistent non-metallic behavior in Sr2IrO4 and Sr3Ir2O7 at high pressures
