The present article reviews recent experimental investigations of spin dynamics in iron-
based superconductors and their parent compounds by means of inelastic neutron …

The discovery of high-temperature superconductivity in a layered iron arsenide has led to an
intensive search to optimize the superconducting properties of iron-based superconductors …

How to achieve supported metal nanocatalysts with simultaneously enhanced activity and
stability is of vital importance in heterogeneous catalysis and remains a challenging goal. In …

This work provides a brief review of the crystal structure, compositional scope, structural
phase transitions, superconductivity, magnetism, and heavy-fermion behavior in the vast …

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 …

Several superconducting transition temperatures in the range of 30–46 K were reported in
the recently discovered intercalated FeSe system (A1-x Fe2-y Se2, A= K, Rb, Cs, Tl) …

Vacancies in solid-state physics are underexplored in materials with strong electron-electron
correlations. Recent research on the Ir-Sb binary system revealed an extended buckled …

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

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 …

The crystal and magnetic structures of the superconducting iron-based chalcogenides Rb y
Fe 2− x Se 2 have been studied by means of single-crystal synchrotron x-ray and high …
