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 …

Since the discovery of high T c iron-based superconductors in early 2008, more than 15,000
papers have been published as a result of intensive research. This paper describes the …

The recently discovered Fe-pnictide and chalcogenide superconductors display low-
temperature properties suggesting superconducting gap structures which appear to vary …

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 …

The physics of sliding friction is gaining impulse from nanoscale and mesoscale
experiments, simulations, and theoretical modeling. This Colloquium reviews some recent …

High-temperature superconductivity in the iron-based materials emerges from, or sometimes
coexists with, their metallic or insulating parent compound states. This is surprising, as these …

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

We analyze antiferromagnetism and superconductivity in novel Fe-based superconductors
within the itinerant model of small electron and hole pockets near (0, 0) and (π, π). We argue …

We study the effect of the lattice structure on the spin-fluctuation-mediated superconductivity
in the iron pnictides adopting the five-band models of several virtual lattice structures of …

A new family of superconductors containing layers of iron arsenide,, has attracted
considerable interest because of their high transition temperatures (T c), some of which are> …
