Superconducting gap and nematic resonance at the quantum critical point observed by Raman scattering in $\mathrm{BaF}{\mathrm{e}}_2({\mathrm{As}}_{1-x}{\mathrm{P}}_x{)}_2$

T. Adachi, M. Nakajima, Y. Gallais +2

We report comprehensive temperature and doping-dependences of the Raman scattering spectra for $\mathrm{BaF}{\mathrm{e}}_2({\mathrm{As}}_{1-x}{\mathrm{P}}_x{)}_2$ ($x=$ 0, 0.07, 0.2…
