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…

Nematic fluctuations and the magneto-structural phase transition in $Ba (F e_{1 - x} C o_{x})_{2} A s_{2}$

Florian Kretzschmar, Thomas Böhm, Una Karahasanović +11

An inelastic light (Raman) scattering study of nematicity and critical fluctuations in $Ba (F e_{1 - x} C o_{x})_{2} A s_{2}$ ( $0 \leq x \leq 0.051$ ) is presented. It is shown that the respon…

A balancing act: Evidence for a strong subdominant d-wave pairing channel in $B a_{0.6} K_{0.4} F e_{2} A s_{2}$

T. Böhm, A. F. Kemper, B. Moritz +7

We present an analysis of the Raman spectra of optimally doped $B a_{0.6} K_{0.4} F e_{2} A s_{2}$ based on LDA band structure calculations and the subsequent estimation of effective R…
