Distinct spin and orbital dynamics in SrRuO
H. Suzuki, L. Wang, J. Bertinshaw +13
The unconventional superconductor SrRuO has long served as a benchmark for theories of correlated-electron materials. The determination of the superconducting pairing mecha…
Competing spin-orbital singlet states in the 4 honeycomb ruthenate AgLiRuO
T. Takayama, M. Blankenhorn, J. Bertinshaw +25
When spin-orbit-entangled -electrons reside on a honeycomb lattice, rich quantum states are anticipated to emerge, as exemplified by the Kitaev materials. Distinct yet equ…
SrIrO/SrIrO superlattice for a model 2D quantum Heisenberg antiferromagnet
Hoon Kim, Joel Bertinshaw, J. Porras +9
Spin-orbit entangled pseudospins hold promise for a wide array of exotic magnetism ranging from a Heisenberg antiferromagnet to a Kitaev spin liquid depending on the lattice and bo…
Formation of orbital molecules on a pyrochlore lattice induced by A-O bond covalency
A. Krajewska, A. Yaresko, J. Nuss +15
The pyrochlore ruthenate InRuO displays a subtle competition between spin-orbital entanglement and molecular orbital formation. At room temperature, a spin-orbit-entang…
Absence of temperature-dependent phonon anomalies in Sr2IrO4 and Sr3Ir2O7
K. Sen, R. Heid, S. M. Souliou +8
Following previous works reporting an anomalous behavior of several zone-center optical phonons across the magnetic transition of square lattice iridates Sr2IrO4 and Sr3Ir2O7, we h…
Reduced crystal symmetry as origin of the ferroelectric polarization within the incommensurate magnetic phase of TbMn2O5
N. Narayanan, P. J. Graham, P. Rovillain +9
The precise crystal symmetry and hence the emergence of the electric polarization still remains an open question in the multiferroic materials MnO ( = rare-earth, Bi,…
Nonmagnetic State and Spin-Orbit Excitations in KRuCl
H. Takahashi, H. Suzuki, J. Bertinshaw +10
Spin-orbit Mott insulators composed of transition metal ions may host excitonic magnetism due to the condensation of spin-orbital triplons. Prior experiments sugge…
Spin and charge excitations in the correlated multiband metal Ca3Ru2O7
J. Bertinshaw, M. Krautloher, H. Suzuki +5
We use Ru -edge resonant inelastic x-ray scattering (RIXS) to study the full range of excitations in CaRuO from meV-scale magnetic dynamics through to the eV-scale…
Proximate ferromagnetic state in the Kitaev model material -RuCl
H. Suzuki, H. Liu, J. Bertinshaw +17
-RuCl is a major candidate for the realization of the Kitaev quantum spin liquid, but its zigzag antiferromagnetic order at low temperatures indicates deviations from the…
Spin-wave gap collapse in Rh-doped Sr2IrO4
J. Bertinshaw, J. K. Kim, J. Porras +7
We use resonant inelastic x-ray scattering (RIXS) at the Ir L3 edge to study the effect of hole doping upon the Jeff=1/2 Mott-insulating state in Sr2IrO4, via Rh replacement of the…
Raman scattering from current-stabilized nonequilibrium phases in CaRuO
K. Fürsich, J. Bertinshaw, P. Butler +3
We used Raman light scattering to study the current-stabilized nonequilibrium semimetallic and metallic phases in CaRuO. By determining the local temperature through carefu…
Spin-orbit-controlled metal-insulator transition in SrIrO
Berend Zwartsenberg, Ryan P. Day, Elia Razzoli +12
In the context of correlated insulators, where electron-electron interactions (U) drive the localization of charge carriers, the metal-insulator transition (MIT) is described as ei…

Over the last few years, SrIrO, a single-layer member of the Ruddlesden-Popper series iridates, has received much attention as a close analog of cuprate high-temperature su…
Pseudospin-lattice coupling in the spin-orbit Mott insulator Sr2IrO4
