Vortex pinning : a probe for nanoscale disorder in iron-based superconductors
Cornelis Jacominus Van Der Beek, Sultan Demirdis, Marcin Konczykowski +5
The pinning of quantized flux lines, or vortices, in the mixed state is used to quantify the effect of impurities in iron-based superconductors (IBS). Disorder at two length scales…
Strong pinning and vortex energy distributions in single crystalline Ba(Fe1-xCox)2As2
S. Demirdis, C. J. van der Beek, Y. Fasano +4
The interrelation between heterogeneity and flux pinning is studied in Ba(Fe1-xCox)2As2 single crystals with widely varying Co-content x. Magnetic Bitter decoration of the supercon…
Incommensurate Spin Density Wave versus local magnetic inhomogeneities in Ba(Fe1-xNix)2As2: a 57Fe Mossbauer spectroscopy study
A. Olariu, P. Bonville, F. Rullier-Albenque +2
We report 57Fe Mossbauer spectral results in pure and doped Ba(Fe1-xNix)2As2 with x=0.01 and 0.03. We show that all these materials present a first-order magnetic transition toward…
Orbitally resolved lifetimes in Ba(Fe0.92Co0.08)2As2 measured by ARPES
V. Brouet, M. Fuglsang Jensen, A. Nicolaou +5
Despite many ARPES investigations of iron pnictides, the structure of the electron pockets is still poorly understood. By combining ARPES measurements in different experimental con…
High Field Studies of Superconducting Fluctuations in High-T_c Cuprates: Evidence for a Small Gap distinct from the Large Pseudogap
F. Rullier-Albenque, H. Alloul, G. Rikken
We have used pulsed magnetic fields up to 60Tesla to suppress the contribution of superconducting fluctuations(SCF)to the conductivity above Tc in a series of YBa2Cu3O6+x from the…
