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 …

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 …

A newly discovered family of Fe-based superconductors is isostructural with the so-called
122 family of Fe pnictides but has a qualitatively different do** state. Early experiments …

We have studied the low-energy spin-excitation spectrum of the single-crystalline Rb 2 Fe 4
Se 5 superconductor (T c= 32 K) by means of inelastic neutron scattering. In the …

Using self-consistent mean-field and functional renormalization-group approaches, we show
that s-wave pairing symmetry is robust in the heavily electron-doped iron chalcogenides A …

We calculate RPA-BCS-based spin resonance spectra of the newly discovered iron-
selenide superconductor by using the two-orbital tight-binding model in a 1-Fe-unit cell. The …

The degree of electron correlations remains a central issue in the iron-based
superconductors. The parent iron pnictides are antiferromagnetic, and their bad-metal …

The electronic structural properties in the presence of constrained magnetization and a
charged background are studied for a monolayer of FeSe in non-magnetic, checkerboard …

Inelastic neutron scattering is employed to study the reciprocal-space structure and
dispersion of magnetic excitations in the normal and superconducting states of single …

The magnetic properties and electronic structure of (K, Tl) y Fe 1.6 Se 2 is studied using first-
principles calculations. The ground state is checkerboard antiferromagnetically coupled …
