Inter- to Intra-Layer Resistivity Anisotropy of NdFeAs(O,H) with Various Hydrogen Concentrations
M. Chen, K. Iida, K. Kondo +3
With molecular beam epitaxy and topotactic chemical reaction, we prepared NdFeAs(O,H) epitaxial thin films with various hydrogen concentrations on 5° vicinal cut MgO substrates. By…
Nanoscale Texture and Microstructure in NdFeAs(O,F)/IBAD-MgO Superconducting Thin Film with Superior Critical Current Properties
Zimeng Guo, Hongye Gao, Keisuke Kondo +5
This paper reports the nanoscale texture and microstructure of a high-performance NdFeAs(O,F) superconducting thin film grown by molecular beam epitaxy on a textured MgO/YO…
High and low anisotropy of hydrogen doped NdFeAsO superconducting thin film
Kazumasa Iida, Jens Hänisch, Keisuke Kondo +6
The recent realisations of hydrogen doped FeAsO (=Nd and Sm) superconducting epitaxial thin films call for further investigation of their structural and electrical transpor…
Anisotropy of the transport properties of NdFeAs(O,F) thin films grown on vicinal substrates
Kazumasa Iida, Takuya Matsumoto, Keisuke Kondo +2
NdFeAs(O,F) thin films having different fluorine contents were grown on 5 deg. or 10 deg. vicinal cut MgO and CaF2 single crystalline substrates by molecular beam epitaxy. Structur…
Grain boundary characteristics of oxypnictide NdFeAs(O,F) superconductors
Kazumasa Iida, Taito Omura, Takuya Matsumoto +2
We have systematically investigated the grain boundary (GB) angle dependence of transport properties for NdFeAs(O,F) fabricated on [001]-tilt symmetric MgO bicrystal substrates. In…
Vortex glass-liquid transition and activated flux motion in an epitaxial, super-conducting NdFeAs(O,F) thin film
J. Hänisch, K. Iida, T. Ohmura +6
An epitaxial NdFeAs(O,F) thin film of 90 nm thickness grown by molecular beam epitaxy on MgO single crystal with Tc = 44.2 K has been investigated regarding a possible vortex glass…
