Fermi-surface of underdoped LaFeAsO1-xFx as determined by the Haas-van Alphen-effect
G. Li, B. S. Conner, S. Weyeneth +7
Here, we present a de Haas-van Alphen (dHvA) effect1 study on the newly discovered LaFeAsO1-xFx compounds2,3 in order to unveil the topography of the Fermi surface associated with…
Th substituted SmFeAsO: structural details and superconductivity with Tc above 50 K
N. D. Zhigadlo, S. Katrych, S. Weyeneth +6
Superconducting poly- and single-crystalline samples of Sm1-xThxFeAsO with partial substitution of Sm3+ by Th4+ were synthesized and grown under high pressure and their structural,…
Inelastic x-ray scattering investigations of lattice dynamics in SmFeAsOF superconductors
M. Le Tacon, T. R. Forrest, Ch. Rüegg +10
We report measurements of the phonon density of states as measured with inelastic x-ray scattering in SmFeAsOF powders. An unexpected strong renormalization of phonon b…
Influence of Mg deficiency in MgB2 single crystals on crystal structure and superconducting properties
N. D. Zhigadlo, S. Katrych, J. Karpinski +4
The effects of high-temperature vacuum-annealing induced Mg deficiency in MgB2 single crystals grown under high pressure were investigated. As the annealing temperature was increas…
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…
Two regimes in the magnetic field response of superconducting MgB
A. Kohen, F. Giubileo, Th. Proslier +10
Using Scanning Tunneling Microscope at low temperature we explore the superconducting phase diagram in the -band of the two-band superconductor MgB. In this band the peculia…
