The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

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 …

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 …

We show that the competition between magnetism and superconductivity can be used to
determine the pairing state in the iron arsenides. To this end we demonstrate that the …

We have studied the superconducting and magnetic properties of Fe 1+ y Se x Te 1− x
single crystals (0≤ x≤ 0.5) by magnetic susceptibility, muon-spin rotation, and neutron …

Local magnetic measurements are used to quantitatively characterize heterogeneity and flux
line pinning in PrFeAsO 1− y and NdFeAs (O, F) superconducting single crystals. In spite of …

Charge density wave (CDW), the periodic modulation of the electronic charge density, will
open a gap on the Fermi surface that commonly leads to decreased or vanishing …

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 …

A crystallographic and magnetic phase diagram of SmFeAsO 1− x F x is determined as a
function of x in terms of temperature based on electrical transport and magnetization …

Superconductors is neither about basic aspects of superconductivity nor about its
applications, but its mainstay is superconducting materials. Unusual and unconventional …
