Robust Charge-Density Wave Correlations in Optimally-Doped YBa2Cu3Oy
Rui Zhou, Igor Vinograd, Hadrien Mayffre +7
Charge-density wave (CDW) order is a key property of high-Tc cuprates, but its boundaries in the phase diagram and potential connections to other phases remain controversial. We re…
Hybridization of lattice and charge order excitations in a superconducting cuprate
S. M. Souliou, D. Ishikawa, R. Heid +9
The ubiquitous tendency of superconducting cuprates to form charge density waves (CDWs) has reignited interest in the nature of their electron-phonon interaction and its role in sh…
In-plane Isotropy of the Low Energy Phonon Anomalies in YBaCuO
Sofia-Michaela Souliou, Kaushik Sen, Rolf Heid +8
We study the temperature dependence of the low energy phonons in the reciprocal plane of the highly ordered ortho-II YBaCuO cuprate high temperature su…
Discovery of Superconductivity in (Ba,K)SbO
Minu Kim, Graham M. McNally, Hun-Ho Kim +12
Superconducting bismuthates (Ba,K)BiO (BKBO) constitute an interesting class of superconductors in that superconductivity with a remarkably high of 30 K arises…
Lattice dynamics and structural transition of the hyperhoneycomb iridate -LiIrO investigated by high-pressure Raman scattering
Sungkyun Choi, Heung-Sik Kim, Hun-Ho Kim +8
We report a polarized Raman scattering study of the lattice dynamics of -LiIrO under hydrostatic pressures up to 7.62 GPa. At ambient pressure, -LiIrO exhibit…
Suppression of superconductivity by charge density wave order in YBaCuO
Mark E. Barber, Hun-ho Kim, Toshinao Loew +6
Hole-doped cuprate superconductors show a ubiquitous tendency towards charge order. Although onset of superconductivity is known to suppress charge order, there has not so far been…
Selective formation of apical oxygen vacancies in LaSrCuO
Gideok Kim, Georg Christiani, Gennady Logvenov +4
The superconducting properties of high-\tc\ materials are functions of carriers concentration, which is controlled by the concentration of defects including heterovalent cations, i…
Compressive-strain induced enhancement of exchange interactions and short-range magnetic order in SrIrO investigated by Raman spectroscopy
A. Seo, P. P. Stavropoulos, H. -H. Kim +7
We have carried out Raman spectroscopy experiments to investigate two-magnon excitations in epitaxial thin films of the quasi-two-dimensional antiferromagnetic Mott insulator Sr$_2…
Site-selective Probe of Magnetic Excitations in Rare-earth Nickelates using Resonant Inelastic X-ray Scattering
Y. Lu, D. Betto, K. Fürsich +11
We have used high-resolution resonant inelastic x-ray scattering (RIXS) to study a thin film of NdNiO, a compound whose unusual spin- and bond-ordered electronic ground state h…
