Since the discovery of iron-based superconductors, a new chapter has been opened in the
history of the development of high temperature superconductivity. In the past decade, there …

In this review, we present a new set of machine learning-based materials research
methodologies for polycrystalline materials developed through the Core Research for …

For cuprate superconductors, a high critical transition temperature (T c) can be realized in
compounds containing multiple CuO2 layers in the unit cell, while a high critical current …

Highlights•A macroscopically ordered phase separation was formed in Fe (Se, Te).•The
special phase separation strengthened the flux pinning behavior of Fe (Se, Te).•A highest J …

Increasing the thickness of a superconducting layer and simultaneously reducing the
thickness effect in iron-based superconducting coated conductors are particularly essential …

It is well known that the existence of interstitial Fe is a great obstacle to enhancing the
superconducting properties of the Fe (Se, Te) system. In this work, a silver and oxygen …

Scanning tunneling microscopy (STM) is a powerful technique for imaging atomic structure
and inferring information on local elemental composition, chemical bonding, and electronic …

FeySexTe1− x targets with different Fe contents have been prepared by the solid state
reaction method followed by the hot-pressed sintering, and corresponding single-phase …

In this study, we have regulated the density of Bi-2212 and Bi-2234 intergrowth layers by
tuning the Cu content. The phase composition and microstructural changes have been …

We report on the superconducting transport properties of B-doped FeSe 0.5 Te 0.5 single
crystals grown by the self-flux method. The structure and superconductivity of these samples …
