Superconductivity is a remarkably widespread phenomenon that is observed in most metals
cooled to very low temperatures. The ubiquity of such conventional superconductors, and …

High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in their …

Films of iron selenide (FeSe) one unit cell thick grown on strontium titanate (SrTiO3 or STO)
substrates have recently shown,,, superconducting energy gaps opening at temperatures …

Superconductivity originates from the formation of bound (Cooper) pairs of electrons that can
move through the lattice without resistance below the superconducting transition …

Understanding spin and lattice excitations in a metallic magnetic ordered system forms the
basis to unveil the magnetic and lattice exchange couplings and their interactions with …

In a superconductor electrons form pairs and electric transport becomes dissipation-less at
low temperatures. Recently discovered iron-based superconductors have the highest …

The symmetry of the wavefunction describing the Cooper pairs is one of the most
fundamental quantities in a superconductor, but for iron-based superconductors it has …

The neutron instruments suite, installed at the spallation neutron source of the Materials and
Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex …

In ultrathin films of FeSe grown on SrTiO3 (FeSe/STO), the superconducting transition
temperature T c is increased by almost an order of magnitude, raising questions on the …

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