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

The commercial availability of the Physical Property Measurement System (PPMS) by
Quantum Design has significantly increased access to heat capacity measurements on a …

The recent discovery of high-temperature superconductivity in single-layer iron selenide has
generated significant experimental interest for optimizing the superconducting properties of …

The multiband nature of iron pnictides gives rise to a rich temperature-do** phase
diagram of competing orders and a plethora of collective phenomena. At low do**s, the …

High-temperature superconductivity is closely adjacent to a long-range antiferromagnet,
which is called a parent compound. In cuprates, all parent compounds are alike and carrier …

A comprehensive study of superconducting properties of underdoped NaFe 0.979 Co 0.021
As single crystals by a combination of upper critical field measurements and incoherent …

We use inelastic neutron scattering to study spin waves in the antiferromagnetic ordered
phase of iron pnictide NaFeAs throughout the Brillouin zone. Comparing with the well …

A determination of the superconducting (SC) electron pairing symmetry forms the basis for
establishing a microscopic mechanism for superconductivity. For iron pnictide …

The characteristics of Fe-based superconductors are manifested in their electronic, magnetic
properties, and pairing symmetry of the Cooper pair, but the latter remain to be explored …

In this paper, the effects of cobalt substitution on the transport and electronic properties of
the recently discovered iron-based superconductor KC a 2 F e 4 A s 4 F 2, with T c= 33 K …
