K-doped Ba122 epitaxial thin film on MgO substrate by buffer engineering
Dongyi Qin, Kazumasa Iida, Zimeng Guo +5
Molecular beam epitaxy of K-doped Ba122 (BaKFeAs) superconductor was realized on a MgO substrate. Microstructural observation revealed that the un…
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…
Approaching the ultimate superconducting properties of (Ba,K)Fe2As2 by naturally formed low-angle grain boundary networks
Kazumasa Iida, Dongyi Qin, Chiara Tarantini +8
The most effective way to enhance the dissipation-free supercurrent in presence of magnetic field for type II superconductors is the introduction of defects that acts as artificial…
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…
Realization of epitaxial thin films of the superconductor K-doped BaFeAs
Dongyi Qin, Kazumasa Iida, Takafumi Hatano +6
The iron-based superconductor BaKFeAs is emerging as a key material for high magnetic field applications owing to the recent developments in super…
