Absence of localized electrons in KTaO interface superconductors
Xinqiang Cai, Jungho Kim, Leonardo Martinelli +19
Recently, an exciting discovery of orientation-dependent superconductivity was made in two-dimensional electron gas (2DEG) at the interfaces of LaAlO/KTaO (LAO/KTO) or EuO/…
RIXS observation of bond-directional nearest-neighbor excitations in the Kitaev material NaIrO
M. Magnaterra, K. Hopfer, Ch. J. Sahle +13
Spin-orbit coupling locks spin direction and spatial orientation and generates, in semi-classical magnets, a local spin easy-axis and associated ordering. Quantum spin-1/2's defy t…
Interplay of broken symmetry and delocalized excitations in the insulating state of 1-TaS
Xun Jia, Anubhab Haldar, Jungho Kim +13
Coexistence of localized and extended excitations is central to the macroscopic properties of correlated materials. For 5d transition metal compounds, electron correlations alone g…
Magnetic Excitations in Square Lattice Iridates: Contrast between BaIrO and SrIrO
J. P. Clancy, H. Gretarsson, A. Lupascu +9
We report a resonant inelastic x-ray scattering (RIXS) investigation of ultra-thin epitaxial films of BaIrO, and compare their low energy magnetic and spin-orbit excitation…
Magnetic excitations in double perovskite iridates LaIrO ( = Co, Ni, and Zn) mediated by 3-5 hybridization
Wentao Jin, Sae Hwan Chun, Jungho Kim +6
By performing resonant inelastic x-ray scattering (RIXS) measurements at the Ir edge, we have investigated the low-energy elementary excitations in a seri…
Magnon-spinon dichotomy in the Kitaev hyperhoneycomb -LiIrO
Alejandro Ruiz, Nicholas P. Breznay, Mengqun Li +16
The family of edge-sharing tri-coordinated iridates and ruthenates has emerged in recent years as a major platform for Kitaev spin liquid physics, where spins fractionalize into em…
