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 …

Electronic correlation is of fundamental importance to high temperature superconductivity.
While the low energy electronic states in cuprates are dominantly affected by correlation …

Through neutron diffraction experiments, including spin-polarized measurements, we find a
collinear incommensurate spin-density wave with propagation vector k=[0.4481 (4) 0 1 2] at …

This volume presents an in-depth review of experimental and theoretical studies of the iron-
based superconductors. Ever since its discovery in 1911, superconductivity, the resistance …

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 …

Spin-polarized scanning tunneling microscopy (SP-STM) has been used extensively to
study magnetic properties of nanostructures. Using SP-STM to visualize magnetic order in …

Using bulk magnetization along with elastic and inelastic neutron scattering techniques, we
have investigated the phase diagram of Fe 1+ y Se x Te 1-x and the nature of magnetic …

The most fundamental limitations of a muon-spin relaxation experiment can be the lack of
knowledge of the implantation site of the muon and the uncertainty about the muon's …

We observed bulk superconductivity in the FeTe 1-x Se x crystals with lower Se
concentrations after annealed in air. A revised magnetism and superconductivity phase …
