Abstract

We report on the temperature dependence of the spatially modulated spin-polarization amplitude ΔKspin, which is a hallmark of the superconducting Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state. For that, we use C13 nuclear magnetic resonance (NMR) spectroscopy performed on the organic conductor β′′-(ET)2SF5CH2CF2SO3. From a comparison of our experimental results to a comprehensive modeling of the C13 NMR spectra, we determine the evolution of ΔKspin upon condensation of the FFLO state. Further, the modeling of the spectra in the superconducting phase allows to quantify the decrease of the average spin susceptibility, stemming from the spin-singlet coupling of the superconducting electron pairs in the FFLO state of β′′-(ET)2SF5CH2CF2SO3. © 2024 American Physical Society.
