Investigation of TiO barriers for their use in hybrid Josephson and tunnelling junctions based on Ba-122 thin films
S. Döring, M. Monecke, S. Schmidt +9
We tested oxidized titanium layers as barriers for hybrid Josephson junctions with high -products and for the preparation of junctions for tunneling spectroscopy. For that…
Influence of the spreading resistance on the conductance spectrum of planar hybrid thin film SNS' junctions based on iron pnictides
S. Döring, S. Schmidt, S. Gottwals +7
To investigate the superconducting properties of iron pnictides we prepared planar hybrid SNS' junctions in thin film technology with a pnictide base electrode, a gold barrier laye…
Surface transport properties of Fe-based superconductors: The influence of degradation and inhomogeneity
T. Plecenik, M. Gregor, R. Sobota +7
Surface properties of Co-doped BaFe2As2 epitaxial superconducting thin films were inspected by X-ray photoelectron spectroscopy, scanning spreading resistance microscopy (SSRM), an…
Bicrystalline Grain Boundary and Hybrid SNS Junctions Based on Ba-122 Thin Films
Stefan Schmidt, Sebastian Döring, Frank Schmidl +6
To investigate the properties of iron-based superconductors, we examined different kinds of Josephson junctions using Co-doped Ba-122 thin films. Based on bicrystalline SrTiO3 subs…
BaFe_{1.8}Co_{0.2}As_2 thin film hybrid Josephson junctions
S. Schmidt, S. Döring, F. Schmidl +7
Josephson junctions with iron pnictides open the way for fundamental experiments on superconductivity in these materials and their application in superconducting devices. Here, we…
Reversible shift in the superconducting transition for La1.85Sr0.15CuO4 and BaFe1.8Co0.2As2 using piezoelectric substrates
Sascha Trommler, Ruben Hühne, Kazumasa Iida +4
The use of piezoelectric substrates enables a dynamic observation of strain dependent properties of functional materials. Based on studies with La1.85Sr0.15CuO4 we extended this ap…
Scaling behaviour of the critical current in clean epitaxial Ba(Fe1-xCox)2As2 thin films
K. Iida, J. Haenisch, T. Thersleff +6
The angular-dependent critical current density, Jc(theta), and the upper critical field, Hc2(theta), of epitaxial Ba(Fe1-xCox)2As2 thin films have been investigated. No Jc(theta) p…
Direct observation of a nodeless superconducting energy gap in the optical conductivity of iron-pnictides
B. Gorshunov, D. Wu, A. A. Voronkov +7
The temperature-dependent optical reflectivity and complex transmissivity of an epitaxially grown Ba(FeCo)As thin film were measured and the optical conduct…
Epitaxial LaFeAsOF thin films grown by pulsed laser deposition
M. Kidszun, S. Haindl, E. Reich +3
Superconducting and epitaxially grown LaFeAsOF thin films were successfully prepared on (001)-oriented LaAlO3 substrates using pulsed laser deposition. The prepared thin films show…
