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…
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…
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 exhib…
