PMID: 18851647
Phys Rev Lett. 2008 Aug 29;101(9):097009. doi: 10.1103/PhysRevLett.101.097009. Epub 2008 Aug 29.

We present zero field and transverse field muon spin relaxation experiments on the recently discovered Fe-based superconductor LaFeAsO1-xFx (x=0.075 and x=0.1). The temperature dependence of the deduced superfluid density is consistent with a BCS s-wave or a dirty d-wave...

We present a detailed study on the magnetic order in the undoped mother compound LaFeAsO of the recently discovered Fe-based superconductor LaFeAsO1-xFx. In particular, we present local probe measurements of the magnetic properties of LaFeAsO by means of 57Fe...

Evolution of two-gap behavior of the superconductor FeSe1-x.

Physical review letters

Khasanov R, Bendele M, Amato A, Conder K, Keller H, Klauss HH, Luetkens H, Pomjakushina E.

Phys Rev Lett. 2010 Feb 26;104(8):087004. doi: 10.1103/PhysRevLett.104.087004. Epub 2010 Feb 25.

The superfluid density, rho{s}, of the iron chalcogenide superconductor, FeSe1-x, was studied as a function of pressure by means of muon-spin rotation. The analysis of rho{s}(T) within the two-gap scheme reveals that the effect on both, the transition temperature...

Impact of external price referencing on medicine prices - a price comparison among 14 European countries.

Southern med review

South Med Rev. 2012 Dec;5(2):34-41. Epub 2012 Dec 27.

OBJECTIVES: This study aims to examine the impact of external price referencing (EPR) on on-patent medicine prices, adjusting for other factors that may affect price levels such as sales volume, exchange rates, gross domestic product (GDP) per capita, total...

Microscopic coexistence of superconductivity and magnetism in Ba(1-x)K(x)Fe2As2.

Physical review letters

Wiesenmayer E, Luetkens H, Pascua G, Khasanov R, Amato A, Potts H, Banusch B, Klauss HH, Johrendt D.

It is widely believed that, in contrast to its electron-doped counterparts, the hole-doped compound Ba(1-x)K(x)Fe(2)As(2) exhibits a mesoscopic phase separation of magnetism and superconductivity in the underdoped region of the phase diagram. Here, we report a combined high-resolution x-ray...

We report the structural and magnetic phase transitions of triclinic Ca10(FeAs)10(Pt3As8), which is the parent compound of the 1038-type iron-arsenide superconductors. High-resolution x-ray diffraction reveals splitting of the in-plane (a,b) lattice parameters at T(s) ≈ 120 K. Platinum-doping weakens...
