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

This article reviews the 40+ year old spin-glass field and one of its earliest model
interpretations as a spin density wave. Our description is from an experimental …

High-temperature superconductivity in iron pnictides and chalcogenides emerges when a
magnetic phase is suppressed. The multi-orbital character and the strength of correlations …

We use nuclear magnetic resonance (NMR), high-resolution x-ray, and neutron scattering
studies to study structural and magnetic phase transitions in phosphorus-doped BaFe 2 (As …

Pnictogens and chalcogens are both viable anions for promoting Fe-based
superconductivity, and intense research activity in the related families has established a …

In Chap. 4, we noted that the emergent incommensurate (IC) short-range antiferromagnetic
(AF) order near optimal superconductivity of Ba (Fe _ 1-x 1-x Co _ xx) _2 2 As _ 2 2 heavily …

We study the effects of disorder on unconventional superconductors in the presence of
correlations, and explore a novel correlated disorder paradigm dominated by strong …

We investigate the effectiveness of the Inverse Laplace Transform (ILT) analysis method to
extract the distribution of relaxation rates from nuclear magnetic resonance data with …

We present evidence for nuclear spin-lattice relaxation driven by glassy nematic fluctuations
in isovalent P-doped BaFe 2 As 2 single crystals. Both the As 75 and P 31 sites exhibit a …

Two ordering states, antiferromagnetism and nematicity, have been observed in most iron-
based superconductors (SCs). In contrast to those SCs, the newly discovered SC CaK (Fe 1 …
