Mesoscopic twin boundaries in epitaxial Ni-Mn-Ga films
Anja Backen, Sandra Kauffmann-Weiss, Christian Behler +6
Twin boundaries play an essential role in the use of magnetic shape memory alloy Ni-Mn-Ga as active material. Only if twin boundaries can be moved by an external magnetic field, hi…
Jc Scaling and Anisotropies in Co-doped Ba-122 thin films
Jens Hänisch, Kazumasa Iida, Silvia Haindl +7
We have successfully grown epitaxial, superconducting films of Ba(Fe1-xCox)2As2 (Ba-122)with x ~ 0.1. The films grow without observable correlated defects parallel to the c-axis, a…
Critical current scaling and anisotropy in oxypnictide superconductors
M. Kidszun, S. Haindl, T. Thersleff +6
Investigating the anisotropy of superconductors permits an access to fundamental properties. Having succeeded in the fabrication of epitaxial superconducting LaFeAs(O,F) thin films…
Evidence for Pauli-limiting behaviour at high fields and enhanced upper critical fields near T_c in several disordered FeAs based Superconductors
G. Fuchs, S. -L. Drechsler, N. Kozlova +11
We report resistivity and upper critical field B_c2(T) data for disordered (As deficient) LaO_0.9F_0.1FeAs_1-delta in a wide temperature and high field range up to 60 T. These samp…
LaFeAsOF thin films: high upper critical fields and evidence of weak link behavior
S. Haindl, M. Kidszun, A. Kauffmann +9
High-quality superconducting LaFeAsOF thin films were grown on single crystalline LaAlO substrates with critical temperatures (onset) up to 28 K. Resistive meas…
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…
