Quantum critical fluctuations in an Fe-based superconductor

Daniel Jost, Leander Peis, Ge He +9

Quantum critical fluctuations may prove to play an instrumental role in the formation of unconventional superconductivity. Here, we show that the characteristic scaling of a margin…

Suppression of Superconductivity and Nematic Order in Fe $_{1 - y}$ Se $_{1 - x}$ S $_{x}$ (0 $\leq$ $x$ $\leq$ 1, $y$ $\leq$ 0.1) Crystals by Anion Height Disorder

Aifeng Wang, Ana Milosavljevic, A. M. Milinda Abeykoon +10

Connections between crystal chemistry and critical temperature $T_{c}$ have been in the focus of superconductivity, one of the most widely studied phenomena in physics, chemistry and…

Phonon anomalies in FeS

A. Baum, A. Milosavljević, N. Lazarević +12

We present results from light scattering experiments on tetragonal FeS with the focus placed on lattice dynamics. We identify the Raman active A1g and B1g phonon modes, a second or…

Superconductivity and fluctuation in Ba $_{1 - p}$ K $_{p}$ Fe $_{2}$ As $_{2}$ and Ba(Fe $_{1 - n}$ Co $_{n}$ ) $_{2}$ As $_{2}$

T. Böhm, R. Hosseinian Ahangharnejhad, D. Jost +9

We study the interplay of fluctuations and superconductivity in BaFe $_{2}$ As $_{2}$ (Ba-122) compounds with Ba and Fe substituted by K ( $p$ doping) and Co ( $n$ doping), respectively. To…

Raman-Scattering Detection of Nearly Degenerate $s$ -Wave and $d$ -Wave Pairing Channels in Iron-Based Ba $_{0.6}$ K $_{0.4}$ Fe $_{2}$ As $_{2}$ and Rb $_{0.8}$ Fe $_{1.6}$ Se $_{2}$ Superconductors

Florian Kretzschmar, Bernhard Muschler, Thomas Böhm +6

We show that electronic Raman scattering affords a window into the essential properties of the pairing potential $V_{k, k^{'}}$ of iron-based superconductors.…
