摘要: We explore the phase diagram of spin-orbit Mott insulators on a honeycomb lattice, within Kitaev-Heisenberg model extended to its full parameter space. Zigzag-type magnetic order is found occupy large part model, and physical origin explained as due interorbital t(2g)-e(g) hopping. The susceptibility, spin wave spectra, zigzag are calculated compared experimental data, obtaining thereby coupling constants in Na(2)IrO(3) Li(2)IrO(3).
