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 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 …

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 experimental studies of magnetism in Fe-based
superconductors. The doping dependent phase diagram shows strong similarities to the …

Antiferromagnetism is relevant to high-temperature (high-T c) superconductivity because
copper oxide and iron arsenide superconductors arise from electron-or hole-doping of their …

Neutron and x-ray diffraction studies show that the simultaneous first-order transition to an
orthorhombic and antiferromagnetic (AFM) ordered state in BaF e 2 As 2 splits into two …

Inelastic neutron scattering measurements on single crystals of superconducting BaFe 1.84
Co 0.16 As 2 reveal a magnetic excitation located at wave vectors (1/2 1/2 L) in tetragonal …

We review the recent developments in electronic Raman scattering measurements of charge
nematic fluctuations in iron-based superconductors. A simple theoretical framework of a d …

We use inelastic neutron scattering to study magnetic excitations of the FeAs-based
superconductor BaFe 1.9 Ni 0.1 As 2 above and below its T c (<? format?>=<? format?> 20 …

Neutron scattering measurements of the magnetic excitations in single crystals of
antiferromagnetic CaFe 2 As 2 reveal steeply dispersive and well-defined spin waves up to …
