Quasi-Two-Dimensional Anomalous Hall Mott Insulator of Topologically Engineered $J_{eff} = 1 / 2$ Electrons

Journal Article Yang, Junyi ; Suwa, Hidemaro ; Meyers, Derek ; ... - Physical Review. X

We investigate an experimental toy-model system of a pseudospin-half square-lattice Hubbard Hamiltonian in [(SrIrO₃)₁/(CaTiO₃)₁] to include both nontrivial complex hopping and moderate electronic correlation. While the former induces electronic Berry phases as anticipated from the weak-coupling limit, the later stabilizes an antiferromagnetic (AFM) Mott insulator ground state in analogous to the strong-coupling limit. Their combined results in the real system are found to be an anomalous Hall effect with a non-monotonic temperature dependence due to the self-competition of the electron-hole pairing in the Mott state, and an exceptionally large Ising anisotropy that is captured as a giant magnon gap beyondmore »« less

Strong anisotropy within a Heisenberg model in the $J_{eff} = \frac{1}{2}$ insulating state of ${Sr}_{2} {Ir}_{0.8} {Ru}_{0.2} O_{4}$

Journal Article Calder, Stuart A. ; Kim, J. W. ; Taylor, Alice E. ; ... - Physical Review B

The dispersive magnetic excitations in Sr2IrO4 have previously been well described within an isospin-1/2 Heisenberg model on a square lattice that revealed parallels with La2CuO4. Here we investigate the inelastic spectra of Sr2Ir0.8Ru0.2O4 with resonant inelastic x-ray scattering (RIXS) at the Ir L3 edge. The results are well described using linear spin-wave theory within a similar Heisenberg model applicable to Sr2IrO4; however, the disorder induced by the substitution of 20%Ir4+ ions for Ru4+ removes longer range exchange interactions. A large spin gap (40 meV) is measured indicating strong anisotropy from spin-orbit coupling that is manifest due to the altered magneticmore »« less
