Evidence for electromagnetic granularity in polycrystalline Sm1111 iron-pnictides with enhanced phase purity
A. Yamamoto, J. Jiang, F. Kametani +7
We prepared polycrystalline SmFeAsO1-xFx (Sm1111) bulk samples by sintering and hot isostatic pressing (HIP) in order to study the effects of phase purity and relative density on t…
Observation of a coherence peak and pair-breaking effects in THz conductivity of BaFeCoAs
R. Valdés Aguilar, L. S. Bilbro, S. Lee +6
We report a study of high quality pnictide superconductor BaFeCoAs thin films using time-domain THz spectroscopy. Near T we find evidence for a coherence…
Conductance asymmetry in point-contacts on epitaxial thin films of Ba(FeCo)As
Manan Mehta, Goutam Sheet, D. A. Dikin +8
Point-contact spectroscopy is a powerful tool for probing superconductors. One of the most common observations in the point-contact spectra on the recently discovered ferropnictide…
Strong vortex pinning in Co-doped BaFe2As2 single crystal thin films
C. Tarantini, S. Lee, Y. Zhang +13
We report measurements of the field and angular dependences of Jc of truly epitaxial Co-doped BaFe2As2 thin films grown on SrTiO3/(La,Sr)(Al,Ta)O3 with different SrTiO3 template th…
Disorder effects and current percolation in FeAs based superconductors
M. Eisterer, M. Zehetmayer, H. W. Weber +7
We report the influence of atomic disorder introduced by sequential neutron irradiation on the basic superconducting properties, flux pinning and grain connectivity. Two different…
