摘要:Besides the charge and spin degrees of freedom, in transition metal compounds the orbital degree of freedom could lead to nontrivial consequences. The relativistic spin-orbit coupling (SOC) promotes the significance of the orbital degree of freedom, and has led to the so called SOC assisted Mott insulator concept in the iridates. If the strong SOC is embedded into special crystal geometry, and consider equal footing competition from hopping, more interesting quantum objects, such as dimer and molecular orbitals, could be realized. Combined with resonant inelastic X-ray scattering measurements and theoretical calculation, we demonstrate the dimer states in Ba5AlIr2O11.
