Abstract

Recently, FeSe_1-xS_x systems have received much attention because of the unique pressure-temperature phase diagram. We performed⁷⁷Se-NMR measurements on a single crystal of FeSe_0.88S_0.12 to investigate its microscopic properties. The shift of⁷⁷Se spectra exhibits anomalous enhancement at 1.0 GPa, suggesting a topological change in the Fermi surfaces, the so-called Lifshitz transition, occurs at 1.0 GPa. The magnetic fluctuation simultaneously changes its properties, which implies a change in the dominant nesting vector.
