The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

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 …

We have investigated the effect of Fe nonstoichiometry on properties of the Fe 1+ y (Te, Se)
superconductor system by means of resistivity, Hall coefficient, magnetic susceptibility, and …

By realizing in thin films a tensile stress state, superconductivity of 13 K was introduced into
FeTe, a nonsuperconducting parent compound of the iron pnictides and chalcogenides, with …

Through neutron diffraction experiments, including spin-polarized measurements, we find a
collinear incommensurate spin-density wave with propagation vector k=[0.4481 (4) 0 1 2] at …

Magnetic properties of iron chalcogenide superconducting materials are investigated using
density-functional calculations. We find that the stability of magnetic phases is very sensitive …

Structural and physical properties of layered chalcogenide superconductors are
summarized. In particular, we review the remarkable properties of the Fe-chalcogenide …

We have performed angle-resolved photoemission spectroscopy of the iron-chalcogenide
superconductor Fe 1.03 Te 0.7 Se 0.3 to investigate the electronic structure relevant to …

We report synthesis of high-quality Fe 1+ y (Te 1− x S x) z single crystals and a
comprehensive study of structural, magnetic, and transport properties. We demonstrate the …

We use neutron scattering to show that spin waves in the iron chalcogenide Fe 1.05 Te
display novel dispersion clearly different from both the first principles density functional …
