The discovery of superconductivity at relatively higher temperatures in a non-cuprate
system, LnFeAsO 1− x F x (Ln= lanthanides) has created tremendous activity among the …

The recent discovery of iron-based superconductors has evoked enthusiasm for extensive
research on these materials because they form the second high-temperature …

We demonstrate the successful fabrication on CaF2 substrates of FeSe1− x Te x films with
0≤ x≤ 1, including the region of 0.1≤ x≤ 0.4, which is well known to be the “phase …

Lattice and electronic states of thin FeSe films on LaAlO 3 substrates are investigated in the
vicinity of the nematic phase transition. No evidence of a structural phase transition is found …

Fe-based superconductors bridge a gap between MgB 2 and the cuprate high temperature
superconductors as they exhibit multiband character and transition temperatures up to …

In order to investigate the effects of in-plane strain on the superconductivity of FeSe,
epitaxial thin films of FeSe were fabricated on CaF 2 substrates. The films are compressed …

Iron chalcogenides are of great interest for both basic physics and high-field applications.
Although their superconducting transition temperatures are typically lower than those of iron …

In-situ epitaxial growth of FeSe 0.5 Te 0.5 thin films is demonstrated on a nonoxide substrate
CaF 2. Structural analysis reveals that compressive stress is moderately added to 36-nm …

The discovery of high-T c superconductivity in Fe-based superconductors pioneered by
Kamihara et al (2008 J. Am. Chem. Soc. 130 3296–7) has triggered worldwide research …

High critical current densities J c of 4 MA/cm 2 at 4 K were obtained in Co-doped BaFe 2 As
2 (BaFe 2 As 2: Co) epitaxial films grown directly on (La, Sr)(Al, Ta) O 3 substrates by pulsed …
