Pressure-induced phase transition and superconductivity in YBa2Cu4O8
S. M. Souliou, A. Subedi, Y. T. Song +4
We investigate the pressure and temperature dependence of the lattice dynamics of the underdoped, stoichiometric, high temperature superconductor YBa2Cu4O8 by means of Raman spectr…
Resonant X-ray Scattering Study of Charge Density Wave Correlations in YBaCuO
S. Blanco-Canosa, A. Frano, E. Schierle +7
We report the results a comprehensive study of charge density wave (CDW) correlations in untwinned YBCO6+x single crystals with 0.4<x<0.99 using Cu-L3 edge resonant x-ray scatterin…
Structural and electronic properties of epitaxial YBaCuO/LaCaMnO bilayers grown on SrTiO (110) substrates
L. Mustafa, N. Driza, S. Soltan M. Le Tacon +2
Epitaxial bilayers of the high-temperature-superconductor YBa2Cu3O7-d (YBCO) and the ferromagnetic metal La0.67Ca0.33MnO3 (LCMO) were prepared by pulsed laser deposition on (110)-o…
Superconductivity-induced Phonon Renormalization on NaFeCoAs
Y. J. Um, Yunkyu Bang, B. H. Min +2
We report a study of the lattice dynamics in superconducting NaFeAs (Tc = 8 K) and doped NaFe0.97Co0.03As (Tc = 20 K) using Raman light scattering. Five of the six phonon modes exp…
Charge order driven by Fermi-arc instability in Bi2201
R. Comin, A. Frano, M. M. Yee +14
The understanding of the origin of superconductivity in cuprates has been hindered by the apparent diversity of intertwining electronic orders in these materials. We combined reson…
