Flux pinning in (1111) iron-pnictide superconducting crystals
C. J. van der Beek, G. Rizza, M. Konczykowski +14
Local magnetic measurements are used to quantitatively characterize heterogeneity and flux line pinning in PrFeAsO_1-y and NdFeAs(O,F) superconducting single crystals. In spite of…
Non-exponential London penetration depth in RFeAsOF (R=La,Nd) single crystals
C. Martin, M. E. Tillman, H. Kim +11
The superconducting penetration depth, , has been measured in RFeAsOF (R=La,Nd) single crystals (R-1111). In Nd-1111, we find an upturn in upon cooling…
Anisotropic London Penetration Depth and Superfluid Density in Single Crystals of Iron-based Pnictide Superconductors
R. Prozorov, M. A. Tanatar, R. T. Gordon +7
In- and out-of-plane magnetic penetration depths were measured in three iron-based pnictide superconducting systems. All studied samples of both 122 systems show a robust power-law…
Upper and lower critical fields in NdFeAs(O,F) single crystals : a study by Hall probe magnetization and specific heat
Z. Pribulova, T. Klein, J. Kacmarcik +5
The upper and lower critical fields have been deduced from specific heat and Hall probe magnetization measurements in non-optimally doped NdFeAs(O,F) single crystals ($T_c \sim 32-…
Effects of Co substitution on thermodynamic and transport properties and anisotropic in Ba(FeCo)As single crystals
N. Ni, M. E. Tillman, J. -Q. Yan +4
Single crystalline samples of Ba(FeCo)As with have been grown and characterized via microscopic, thermodynamic and transport measurements. With incre…
Momentum dependence of the superconducting gap in NdFeAsO1-xFx single crystals measured by angle resolved photoemission spectroscopy
Takeshi Kondo, A. F. Santander-Syro, O. Copie +8
We use angle resolved photoemission spectroscopy (ARPES) to study the momentum dependence of the superconducting gap in NdFeAsO1-xFx single crystals. We find that the Gamma hole po…
