From: Pressure-induced reconstitution of Fermi surfaces and spin fluctuations in S-substituted FeSe
Typical \(^{77}\)Se-NMR spectra and linewidth for 12% S-substituted FeSe corresponding to the nematic and antiferromagnetic (AF) orders. (a) The NMR spectra at ambient pressure show a double-edge structure in the nematic phase below 60 K20. The NMR spectra at 3.9 GPa broaden remarkably, and the signal is not observed below the AF transition temperature \(T_{\mathrm{N}}\). (b) Full width at half maximum at 3.5 and 3.9 GPa. The arrows shown by \(T_{\mathrm{nem}}\) and \(T_{\mathrm{c}}\) represent the nematic and superconducting transition temperatures, respectively20.
