Correlation between Superconductivity and Magnetic Fluctuations in Fe(Se1-xSx) Revealed by 77Se NMR

P. Wiecki, K. Rana, A. E. Böhmer +4

We present ${}^{77}$Se-NMR measurements on FeSe${}_{1-x}$S${}_x$ samples with sulfur content $x=0,9,15$ and $29\%$. Twinned nematic domains are observed in the NMR spectrum for all sampl…
