We have studied the evolution of magnetic and orbital excitations as a function of hole-doping in single crystal samples of Sr2Ir(1-x)Rh(x)O4 (0.07 < x < 0.42) using high resolution Ir L3-edge resonant inelastic x-ray scattering (RIXS). Within the antiferromagnetically ordered region of the phase diagram (x < 0.17) we observe highly dispersive magnon and spin-orbit exciton modes. Interestingly, both the magnon gap energy and the magnon bandwidth appear to increase as a function of doping… Expand

Strain engineering of the charge and spin-orbital interactions in Sr2IrO4
This work highlights the central role played by the lattice degrees of freedom in determining both the pseudospin and charge excitations of Sr2IrO4 and provides valuable information toward the control of the ground state of complex oxides in the presence of high spin–orbit coupling. Expand
High-resolution resonant inelastic x-ray scattering study of the electron-phonon coupling in honeycomb α−Li2IrO3
The excitations in honeycomb $\alpha$-Li$_2$IrO$_3$ have been investigated with high-resolution resonant inelastic x-ray scattering (RIXS) at the O K edge. The low-energy response is dominated by aExpand

Charge partitioning and anomalous hole doping in Rh-doped Sr2IrO4
The simultaneous presence of sizable spin-orbit interactions and electron correlations in iridium oxides has led to predictions of novel ground states including Dirac semimetals, Kitaev spin liquids,Expand
Spin-orbit tuned metal-insulator transitions in single-crystal Sr2Ir1−xRhxO4(0≤x≤1)
Sr₂IrO₄ is a magnetic insulator driven by spin-orbit interaction (SOI) whereas the isoelectronic and isostructural Sr₂RhO₄ is a paramagnetic metal. The contrasting ground states have been shown toExpand
Observation of a d-wave gap in electron-doped Sr2IrO4
Sr2IrO4 bears a striking electronic resemblance to the cuprate superconductors, except the iridate is an insulator. Introducing electrons into Sr2IrO4 leads to a d-wave gap, suggestingExpand
Correlation induced electron-hole asymmetry in quasi- two-dimensional iridates
It is shown that there is significant electron-hole asymmetry in iridates, contrary to expectations from the cuprates, which demonstrates that correlation physics renders electron- and hole-doped iridates fundamentally different. Expand
Persistence of magnetic excitations in La(2-x)Sr(x)CuO4 from the undoped insulator to the heavily overdoped non-superconducting metal.
One of the most intensely studied scenarios of high-temperature superconductivity (HTS) postulates pairing by exchange of magnetic excitations. Indeed, such excitations have been observed up toExpand
High-energy spin and charge excitations in electron-doped copper oxide superconductors.
X-ray and neutron inelastic X-ray scattering spectra show that magnetic excitations shift to higher energy upon doping, and they deeply mix with charge excitations, indicating that electrons acquire a highly itinerant character in the doped metallic state. Expand
Crystal-field splitting and correlation effect on the electronic structure of A2IrO3.
The electronic structure of the honeycomb lattice iridates Na(2)IrO(3) and Li(2), which have been investigated using resonant inelastic x-ray scattering (RIXS), suggest that both can be described as spin-orbit Mott insulators, similar to the square lattice IrO(4). Expand

Persistent spin excitations in doped antiferromagnets revealed by resonant inelastic light scattering.
It is shown that RIXS at the Cu L3-edge indeed provides access to the spin dynamical structure factor once one considers the full influence of light polarization, and it is demonstrated that high-energy spin excitations do not correlate with the doping dependence of Tc, while low-energy excitations depend sensitively on doping and show ferromagnetic correlations.
