What is Spin-Orbital States in Strong Coupling about?
This paper investigates the ground state properties of a t2g-orbital Hubbard model with strong spin-orbit coupling, revealing a transition from a spin singlet state to a weak ferromagnetic state characterized by an effective total angular momentum. The emergence of a complex orbital state, where real xy, yz, and zx orbitals mix with complex coefficients, is observed as the spin-orbit coupling increases. The findings contribute to understanding novel magnetism in 5d transition metal oxides like Sr2IrO4.
