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

Fe-based superconductors bridge a gap between MgB 2 and the cuprate high temperature
superconductors as they exhibit multiband character and transition temperatures up to …

We present a comprehensive study of the low-temperature heat capacity and thermal
expansion of single crystals of the hole-doped Ba 1− x K x Fe 2 As 2 series (0< x< 1) and the …

A single crystal of isovalently substituted Ba (Fe 1− x Ru x) 2 As 2 (x= 0.24) is sequentially
irradiated with 2.5 MeV electrons up to a maximum dose of 2.1× 1 0 19 e−/cm 2. The …

With the discovery of charge-density waves (CDWs) in most members of the cuprate high-
temperature superconductors, the interplay between superconductivity and CDWs has …

A highly anisotropic superconducting gap is found in single crystals of FeSe by studying the
London penetration depth Δ λ measured down to 50 mK in samples before and after 2.5 …

High-energy electron irradiation at low temperatures is an efficient and controlled way to
create vacancy–interstitial Frenkel pairs in a crystal lattice, thereby inducing nonmagnetic …

The role of anharmonicity on superconductivity has often been disregarded in the past.
Recently, it has been recognized that anharmonic decoherence could play a fundamental …

One of the open issues concerning iron-based superconductors is whether the s±wave
model is able to account for the overall effects of impurity scattering, including the low rate of …

In most iron-based superconductors, the transition to the magnetically ordered state is
closely linked to a lowering of structural symmetry from tetragonal (C 4) to orthorhombic (C …
