Doping and critical-temperature dependence of the energy gaps in Ba(Fe_{1-x}Co_x)_2As_2 thin films
P. Pecchio, D. Daghero, G. A. Ummarino +4
The dependence of the superconducting gaps in epitaxial Ba(Fe_{1-x}Co_{x})_2As_2 thin films on the nominal doping x (0.04 \leq x \leq 0.15) was studied by means of point-contact An…
Oxypnictide SmFeAs(O,F) superconductor: a candidate for high-field magnet applications
Kazumasa Iida, Jens Haenisch, Chiara Tarantini +10
The recently discovered oxypnictide superconductor SmFeAs(O,F) is the most attractive material among the Fe-based superconductors due to its highest transition temperature of 56 K…
Intrinsic pinning and the critical current scaling of clean epitaxial Fe(Se,Te) thin films
Kazumasa Iida, Jens Haenisch, Elke Reich +11
We report on the transport properties of clean, epitaxial Fe(Se,Te) thin films prepared on Fe-buffered MgO (001) single crystalline substrates by pulsed laser deposition. Near Tc a…
BaFe2As2/Fe bilayers with [001]-tilt grain boundary on MgO and SrTiO3 bicrystal substrates
Kazumasa Iida, Silvia Haindl, Fritz Kurth +3
Co-doped BaFe2As2 (Ba-122) can be realized on both MgO and SrTiO3 bicrystal substrates with [001]-tilt grain boundary by employing Fe buffer layers. However, an additional spinel (…
Versatile fluoride substrates for Fe-based superconducting thin films
Fritz Kurth, Elke Reich, Jens Hänisch +8
We demonstrate the growth of Co-doped BaFe2As2 (Ba-122) thin films on AEF2 (001) (AE: Ca, Sr, Ba) single crystal substrates using pulsed laser deposition. All films are grown epita…
The order-parameter symmetry and Fermi surface topology of 122 Fe-based superconductors: a point-contact Andreev-reflection study
R. S. Gonnelli, M. Tortello, D. Daghero +8
We report on the results of directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe_{1-x}Co_x)2As2 single crystals and epitaxial c-axis oriented films with x = 0.…
