Frustrated transition-metal compounds in which spin-orbit coupling (SOC) and electron correlation work together have attracted much attention recently. In the case of $5d$ transition metals, where SOC is large, ${j}_{\text{eff}}=1/2$ bands near the Fermi level are thought to encompass the essential physics of the material, potentially leading to a concrete realization of exotic magnetic phases such as the Kitaev spin liquid. Here, we derive a spin model on a triangular lattice based on ${j}_… 31 Citations ## Figures from this paper Kitaev materials • Materials Science, Physics Physics Reports • 2022 Comprehensive study of the global phase diagram of the J−K−Γ model on a triangular lattice • Materials Science, Mathematics • 2021 The celebrated Kitaev honeycomb model provides an analytically tractable example with an exact quantum spin liquid ground state.
