摘要The intrachain magnetic interaction and the electronic structure of Sr3NiIrO6 are investigated by performing the first-principles density functional calculations. The results show that the interaction between Ir and Ni is antiferromagnetic in each quasi-one-dimensional chain. More importantly, the GGA+U calculations hardly reproduce the insulating characteristics of Sr3NiIrO6 in the region of reasonable correlation parameter. Interestingly, the spin-orbit coupling (SOC) together with the electron-electron correlation (GGA+SOC+U) can lead to the insulating characteristics of Sr3NiIrO6. This provides apparent evidence that Sr3NiIrO6 belongs to a new category of insulator: SOC induced Mott insulator. (C) 2010 American Institute of Physics. [doi:10.1063/1.3360339]
