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…
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…
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…
Universal scaling behavior of the upper critical field in strained FeSe0.7Te0.3 thin films
Feifei Yuan, Vadim Grinenko, Kazumasa Iida +12
Revealing the universal behaviors of iron-based superconductors (FBS) is important to elucidate the microscopic theory of superconductivity. In this work, we investigate the effect…
Intrinsic charge dynamics in high-Tc AFeAs(O,F) superconductors
A. Charnukha, D. Pröpper, N. D. Zhigadlo +8
We report the first determination of the in-plane complex optical conductivity of 1111 high-Tc superconducting iron oxypnictide single crystals PrFeAsO0.6F0.35 and thin films SmFeA…
The influence of the in-plane lattice constant on the superconducting transition temperature of FeSe0.7Te0.3 thin films
Feifei Yuan, Kazumasa Iida, Vadim Grinenko +12
Epitaxial Fe(Se,Te) thin films were prepared by pulsed laser deposition on (La0.18Sr0.82)(Al0.59Ta0.41)O3 (LSAT), CaF2-buffered LSAT and bare CaF2 substrates, which exhibit an almo…
