Nematic spin correlations pervading the phase diagram of FeSe${}_{1-x}$S${}_x$

Ruixian Liu, Wenliang Zhang, Yuan Wei +8

We use resonant inelastic X-ray scattering (RIXS) at the Fe-L${}_3$ edge to study the spin excitations of uniaxial-strained and unstrained FeSe${}_{1-x}$S${}_x$ ($0\le x\le 0.21$) sam…
