Probing the ground state and the Van Vleck paramagnetism of the Ir ions in the layered SrCoIrO
S. Agrestini, C. -Y. Kuo, K. Chen +11
We report a combined experimental and theoretical x-ray magnetic circular dichroism (XMCD) spectroscopy study at the Ir- edges on the Ir ions of the layered hybrid…
Long-range interactions in the effective low energy Hamiltonian of Sr2IrO4: a core level resonant inelastic x-ray scattering study
S. Agrestini, C. -Y. Kuo, M. Moretti Sala +12
We have investigated the electronic structure of Sr2IrO4 using core level resonant inelastic x-ray scattering. The experimental spectra can be well reproduced using ab initio densi…
Model analysis of magnetic susceptibility of SrIrO - 2D = 1/2 Heisenberg system with competing interlayer couplings
Tomohiro Takayama, Akiyo Matsumoto, George Jackeli +1
We report the analysis of magnetic susceptibility () of SrIrO single crystal in the paramagnetic phase. We formulate the theoretical susceptibility based on isotropic…
Optical anisotropy of the Jeff = 1/2 Mott insulator Sr2IrO4
D. Pröpper, A. N. Yaresko, M. Höppner +7
We report the complex dielectric function along and perpendicular to the IrO2 planes in the layered perovskite Sr2IrO4 determined by spectroscopic ellipsometry in the spectral rang…
Pseudospin heat conductivity in the antiferromagnet SrIrO
Frank Steckel, Akiyo Matsumoto, Tomohiro Takayama +3
We report the in-plane and out-of-plane heat conductivity of the antiferromagnetic spin-orbit induced Mott insulator SrIrO with . Our data reveal clea…
Low energy magnetic excitations in the spin-orbital Mott insulator SrIrO
S. Bahr, A. Alfonsov, G. Jackeli +6
We report a high-field electron spin resonance study in the sub-THz frequency domain of a single crystal of SrIrO that has been recently proposed as a prototypical spin-orb…
Spin-orbit coupling induced semi-metallic state in the 1/3 hole doped hyper-kagome Na3Ir3O8
T. Takayama, A. Matsumoto, J. Nuss +5
The complex iridium oxide Na3Ir3O8 with a B-site ordered spinel structure was synthesized in single crystalline form, where the chiral hyper-kagome lattice of Ir atoms, as observed…
Fano Resonances in the Infrared Spectra of Phonons in Hyper-Kagome Na_3Ir_3O_8
D. Pröpper, A. N. Yaresko, T. I. Larkin +7
We report the complex dielectric function of high-quality Na_3Ir_3O_8 single crystals determined by spectroscopic ellipsometry in the spectral range from 15 meV to 2 eV. The far-in…
