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…
Effect of columnar defects on the pinning properties of NdFeAsO0.85 conglomerate particles
J. D. Moore, L. F. Cohen, Y. Yeshurun +12
Oxypnictide superconductor NdFeAsO0.85 sample was irradiated with 2 GeV Ta ions at a fluence of 5x10^10 ions/cm2. High resolution transmission electron microscopy study revealed th…
Superconductivity at 55 K in iron-based F-doped layered quaternary compound Sm[O1-xFx]FeAs
Zhi-An Ren, Wei Lu, Jie Yang +8
Here we report the superconductivity in the iron-based oxyarsenide Sm[O1-xFx]FeAs, with the onset resistivity transition temperature at 55.0 K and Meissner transition at 54.6 K. Th…
Pressure Effect on the superconducting properties of LaO_{1-x}F_{x}FeAs(x=0.11) superconductor
W. Lu, J. Yang, X. L. Dong +3
Diamagnetic susceptibility measurements under high hydrostatic pressure (up to 1.03 GPa) were carried out on the newly discovered Fe-based superconductor LaO_{1-x}F_{x}FeAs(x=0.11)…
Superconductivity at 52 K in iron-based F-doped layered quaternary compound Pr[O1-xFx]FeAs
Zhi-An Ren, Jie Yang, Wei Lu +5
Since the discovery of copper oxide superconductor in 1986 [1], extensive efforts have been devoted to the search of new high-Tc superconducting materials, especially high-Tc syste…
Quantum tunneling of vortices in a MgB superconductor
Y. Z. Zhang, R. Deltour, H. H. Wen +5
Magnetic relaxation in a MgB superconductor was measured. The temperature dependence of the normalized relaxation rate was determined for three different magnetic fields. By ex…
