Probing the Lattice Anharmonicity of Superconducting YBaCuO Via Phonon Harmonics
Alberto Ramos-Alvarez, Nina Fleischmann, Luciana Vidas +3
We examine coherent phonons in a strongly driven sample of optimally-doped high temperature superconductor YBaCuO. We observe a non-linear lattice response of the 4…
The conductivity and the magnetization around Tc in optimally-doped YBaCuO revisited: quantitative analysis in terms of fluctuating superconducting pairs
R. I. Rey, C. Carballeira, J. M. Doval +7
We first present detailed measurements of the rounding behavior around the superconducting transition temperature, , of the in-plane electrical conductivity, magnetoconductivi…
Quasi-1-Dimensional Superconductivity in Highly Disordered NbN Nanowires
K. Yu. Arutyunov, A. Ramos-Álvarez, A. V. Semenov +6
The topic of superconductivity in strongly disordered materials has attracted a significant attention. In particular vivid debates are related to the subject of intrinsic spatial i…
Superconducting fluctuations in isovalently-substituted BaFe(AsP): Possible observation of multiband effects
A. Ramos-Álvarez, J. Mosqueira, F. Vidal +4
The nature of superconducting fluctuation effects in the isovalently-substituted iron pnictide BaFe(AsP) (x=0.35) is probed through measurements of the magnetiz…
Magnetic field dependence of the precursor diamagnetism in La superconductors with magnetic Pr impurities
F. Soto, C. Carballeira, J. M. Doval +6
The interplay between fluctuating Cooper pairs and magnetic impurities in conventional BCS low-Tc superconductors has been studied through measurements of the magnetic field depend…
Large increase of the anisotropy factor in the overdoped region of Ba(FeNi)As as probed by fluctuation spectroscopy
A Ramos-Álvarez, J Mosqueira, F Vidal +2
We study the diamagnetism induced by thermal fluctuations above the superconducting transition of the iron pnictide Ba(FeNi)As with different doping levels. The…
