Momentum-dependent charge correlations in YBaCuO superconductors probed by resonant x-ray scattering: Evidence for three competing phases
S. Blanco-Canosa, A. Frano, T. Loew +10
We have used resonant x-ray scattering to determine the momentum dependent charge correlations in YBaCuO samples with highly ordered chain arrays of oxygen accepto…
Electric-field-induced pyroelectric order and localization of the confined electrons in LaAlO3/SrTiO3 heterostructures
M. Rössle, K. W. Kim, A. Dubroka +13
With infrared ellipsometry, x-ray diffraction, and electric transport measurements we investigated the electric-field-effect on the confined electrons at the LaAlO3/SrTiO3 interfac…
Long-range incommensurate charge fluctuations in (Y,Nd)Ba2Cu3O(6+x)
G. Ghiringhelli, M. Le Tacon, M. Minola +17
There are increasing indications that superconductivity competes with other orders in cuprate superconductors, but obtaining direct evidence with bulk-sensitive probes is challengi…
Distinct Charge Orders in the Planes and Chains of Ortho-III-Ordered YBaCuO Superconductors Identified by Resonant Elastic X-ray Scattering
A. J. Achkar, R. Sutarto, X. Mao +15
Recently, charge density wave (CDW) order in the CuO planes of underdoped YBaCuO was detected using resonant soft x-ray scattering. An important question remain…
