Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

The iron-based superconductors that contain FeAs layers as the fundamental building block
in the crystal structures have been rationalized in the past using ideas based on the Fermi …

Advanced synchrotron radiation focusing down to a size of 300 nm has been used to
visualize nanoscale phase separation in the K 0.8 Fe 1.6 Se 2 superconducting system …

Superconductors with exotic physical properties are critical to current and future technology.
In this review, we highlight several important superconducting families and focus on their …

In this review, we present a summary of results on single crystal growth of two types of iron-
chalcogenide superconductors, Fe 1+ y Te 1− x Se x (11), and A x Fe 2− y Se 2 (A= K, Rb …

The correlation and competition between antiferromagnetism and superconductivity are one
of the most fundamental issues in high temperature superconductors. Superconductivity in …

Superconductivity in iron selenides has experienced a rapid growth, but not without major
inconsistencies in the reported properties. For alkali-intercalated iron selenides, even the …

We successfully grew the high-quality single crystals of A x Fe 2 Se 2 (A= K and Cs) by self-
flux method. Sharp superconducting transition was observed for both types of crystals. The …

We report the preparation of single crystals of tetragonal iron sulfide (FeS) which exhibits a
nearly ideal tetrahedral geometry with S–Fe–S bond angles of 110.2 (2)∘ and 108.1 (2)∘ …

We report here that a new superconducting phase with much higher Tc has been found in K
intercalated FeSe compound with excess Fe. We successfully grew crystals by precisely …
