Fabrication of FeSe1-x superconducting films with bulk properties
Soon-Gil Jung, Nam Hoon Lee, Eun-Mi Choi +4
We have fabricated high-quality FeSe1-x superconducting films with a bulk Tc of 11-12 K on different substrates, Al2O3(0001), SrTiO3(100), MgO(100), and LaAlO3(100), by using a pul…
Very strong intrinsic supercurrent carrying ability and vortex avalanches in (Ba,K)Fe2As2 superconducting single crystals
Xiao-Lin Wang, S. R. Ghorbani, Sung-Ik Lee +9
We report that single crystals of (Ba,K)Fe2As2 with Tc = 32 K have a pinning potential, U0, as high as 10^4 K, with U0 showing very little field depend-ence. In addition, the (Ba,K…
In-situ fabrication of cobalt-doped SrFe2As2 thin films by using pulsed laser deposition with excimer laser
Eun-Mi Choi, Soon-Gil Jung, Nam Hoon Lee +6
The remarkably high superconducting transition temperature and upper critical field of iron(Fe)-based layered superconductors, despite ferromagnetic material base, open the prospec…
Concurrent Magnetic and Metal-Insulator Transitions in (Eu,Sm)B_6 Single Crystals
S. Yeo, J. E. Bunder, Hsiu-Hau Lin +2
The effects of magnetic doping on a EuB_6 single crystal were investigated based on magnetic and transport measurements. A modest 5% Sm substitution for Eu changes the magnetic and…
Unconventional superconductivity of NdFeAsO0.82F0.18 indicated by the low temperature dependence of the lower critical field Hc1
X. L. Wang, S. X. Dou, Zhi-An Ren +4
We measured the initial M-H curves for a sample of the newly discovered superconductor NdFeAsO0.82Fe0.18, which had a critical temperature, Tc, of 51 K, and was fabricated at the h…
Avalanches Injecting Flux into the Central Hole of a Superconducting MgB2 Ring
Age Andreas Falnes Olsen, Tom Henning Johansen, Daniel Shantsev +4
Magneto-optical imaging was used to observe dendritic flux avalanches connecting the outer and inner edges of a ring-shaped superconducting MgB2 film. Such avalanches create heated…
