Damping of dHvA oscillations and vortex-lattice disorder in the peak-effect region of strong type-II superconductors
A. Maniv, T. Maniv, V. Zhuravlev +6
The phenomenon of magnetic quantum oscillations in the superconducting state poses several questions that still defy satisfactory answers. A key controversial issue concerns the ad…

Growth and characterization of epitaxial LuNi2B2C thin films on MgO single crystals
T. Niemeier, R. Hühne, A. Köhler +3
Biaxially textured LuNi2BC thin films with Tc up to 15.8 K and a residual resistivity ratio up to 15 have been prepared. The films were deposited on MgO(110) substrates using pulse…

Orbital and spin effects for the upper critical field in As deficient disordered Fe pnictide superconductors
G. Fuchs, S. -L. Drechsler, N. Kozlova +17
We report B_c2 data for LaO_{0.9}F_{0.1}FeAs_{1-delta} in a wide T and field range up to 60 Tesla. The large slope of B_c2 approx ~ -6 Tesla/K near an improved T_c = 28.5 K of the…
