Evolution of spin excitations in superconducting LaCaCuO from the underdoped to the heavily overdoped regime
S. Hameed, Y. Liu, M. Knauft +8
We investigate high-energy spin excitations in hole-doped LaCaCuO films across a broad Ca doping range using resonant inelastic x-ray scatteri…
Dynamical interplay between superconductivity and charge-density-wave: a nonlinear terahertz study of coherently-driven 2H-NbSe2 and La2-xSrxCuO4
Liwen Feng, Jiayuan Cao, Tim Priessnitz +21
2H-NbSe2 is an archetypal system in which superconductivity and charge-density-wave (CDW) coexist and compete macroscopically with each other. In particular, this interplay also ma…
Fano interference of the Higgs mode in cuprate high-Tc superconductors
Hao Chu, Sergey Kovalev, Zi Xiao Wang +31
Despite decades of search for the pairing boson in cuprate high-Tc superconductors, its identity still remains debated to date. For this reason, spectroscopic signatures of electro…
Approaching two-dimensional superconductivity in ultrathin DyBaCuO
R. D. Dawson, K. S. Rabinovich, D. Putzky +4
The temperature dependence of the superfluid density has been measured for a series of ultrathin MBE-grown DyBaCuO superconducting (SC) films by sub-mm wav…
Imprint of charge and oxygen orders on Dy ions in DyBaCuO thin films probed by resonant x-ray scattering
Davide Betto, Martin Bluschke, Daniel Putzky +8
We used resonant elastic x-ray scattering at the Cu and Dy edges to investigate charge order in thin films of underdoped DyBaCuO (DyBCO) epitaxially gro…
Electronic and vibrational signatures of ruthenium vacancies in SrRuO thin films
Gideok Kim, Y. Eren Suyolcu, J. Herrero-Martin +12
The synthesis of stoichiometric SrRuO thin films has been a challenge because of the high volatility of ruthenium oxide precursors, which gives rise to ruthenium vacancies…
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…
Observation of superconducting current in a mesa-heterostructure with an interlayer of the strontium iridate film with strong spin-orbit interaction
A. M. Petrzhik, K. Y. Constantinian, G. A. Ovsyannikov +5
The superconducting current has been observed in mesa-heterostructures Nb/Au/Sr2IrO4/YBa2Cu3Ox with Sr2IrO4 interlayer thickness d=5 and 7 nm and in-plane sizes L=10-50 mcm. A stro…
The temperature-dependent magnetization profile across an epitaxial bilayer of ferromagnetic La2/3Ca1/3MnO3 and superconducting YBa2Cu3O7-d
S. Brück, S. Treiber, S. Macke +6
Epitaxial bilayers of ferromagnetic La2/3Ca1/3MnO3 (LCMO) and superconducting YBa2Cu3O7-d (YBCO) have been grown on single-crystalline SrTiO3 (STO) substrates by pulsed laser depos…
Superconductivity in epitaxial thin films of NaxCoO2 y D2O
Y. Krockenberger, I. Fritsch, G. Christiani +5
The observation of superconductivity in the layered transition metal oxide NaxCoO2 y H2O (K. Takada et al., Nature 422, 53 (2003)) has caused a tremendous upsurge of scientific int…
