Enhancement of the Superconducting Transition Temperature in FeSe Epitaxial Thin Films by Anisotropic Compression
Fuyuki Nabeshima, Yoshinori Imai, Masafumi Hanawa +2
In order to investigate the effects of in-plane strain on the superconductivity of FeSe, epitaxial thin films of FeSe were fabricated on CaF substrates. The films are compresse…
Effect of Vacuum Annealing on Superconductivity in Fe(Se,Te) Single Crystals
Seiki Komiya, Masafumi Hanawa, Ichiro Tsukada +1
The effect of vacuum annealing on superconductivity is investigated in Fe(Se,Te) single crystals. It is found that superconductivity is not enhanced by annealing under high vacuum…
Intrinsic pinning and the critical current scaling of clean epitaxial Fe(Se,Te) thin films
Kazumasa Iida, Jens Haenisch, Elke Reich +11
We report on the transport properties of clean, epitaxial Fe(Se,Te) thin films prepared on Fe-buffered MgO (001) single crystalline substrates by pulsed laser deposition. Near Tc a…
Microscopic analysis of the chemical reaction between Fe(Te,Se) thin films and underlying CaF
A. Ichinose, I. Tsukada, M. Hanawa +5
To understand the chemical reaction at the interface of materials, we performed a transmission electron microscopy (TEM) observation in four types of Fe(Te,Se) superconducting thin…
Epitaxial growth of FeSeTe thin films on CaF substrates with high critical current density
I. Tsukada, M. Hanawa, T. Akiike +8
In-situ epitaxial growth of FeSeTe thin films is demonstrated on a non-oxide substrate CaF. Structural analysis reveals that compressive stress is moderately ad…
Hall effect of FeTe and Fe(Se_1-x_Te_x_) thin films
I. Tsukada, M. Hanawa, Seiki komiya +4
The Hall effect is investigated in thin-film samples of iron-chalcogenide superconductors in detail. The Hall coefficient (RH) of FeTe and Fe(Se1-xTex) exhibits a similar positive…
