High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in 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 present article reviews recent experimental investigations of spin dynamics in iron-
based superconductors and their parent compounds by means of inelastic neutron …

The iron chalcogenides FeSe and FeS are superconductors composed of two-dimensional
sheets held together by van der Waals interactions, which makes them prime candidates for …

We used low-temperature synchrotron x-ray diffraction to investigate the structural phase
transitions of Fe 1+ y Te in the vicinity of a tricitical point in the phase diagram. A detailed …

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)∘ …

Our inelastic neutron scattering study of spin excitations in iron telluride reveals remarkable
thermal evolution of the collective magnetism. In the temperature range relevant for the …

Phase diagrams play a primary role in the understanding of materials properties. For iron-
based superconductors (Fe-SC), the correct definition of their phase diagrams is crucial …

High-temperature superconductivity in both the copper-oxide and the iron–
pnictide/chalcogenide systems occurs in close proximity to antiferromagnetically ordered …

Magnetic phenomena in chemistry and condensed matter physics are considered to be
associated with low temperatures. That a magnetic state or order is stable below a critical …
