New Fe-based superconductors: properties relevant for applications
M Putti, I Pallecchi, E Bellingeri +23
Less than two years after the discovery of high temperature superconductivity in oxypnictide LaFeAs(O,F) several families of superconductors based on Fe layers (1111, 122, 11, 111)…
Template engineering of Co-doped BaFe2As2 single-crystal thin films
S. Lee, J. Jiang, C. T. Nelson +14
Understanding new superconductors requires high-quality epitaxial thin films to explore intrinsic electromagnetic properties, control grain boundaries and strain effects, and evalu…
Intergrain current flow in a randomly oriented polycrystalline SmFeAsO0.85 oxypnictide
F. Kametani, P. Li, D. Abraimov +11
We report a direct current transport study of the local intergrain connections in a polycrystalline SmFeAsO0.85 (Sm1111) bulk, for which we earlier estimated significant intergranu…
Weak-link behavior of grain boundaries in superconducting Ba(Fe1-xCox)2As2 bicrystals
S. Lee, J. Jiang, J. D. Weiss +17
We show that despite the low anisotropy, strong vortex pinning and high irreversibility field Hirr close to the upper critical field Hc2 of Ba(Fe1-xCox)2As2, the critical current d…
Neutron Irradiation of Sm-1111
M. Eisterer, H. W. Weber, J. Jiang +5
SmFeAsOF was irradiated in a fission reactor to a fast (E > 0.1 MeV) neutron fluence of 4x10^ m. The introduced defects increase the normal state resistivi…
