${}^{19}$F NMR and defect spins in vacuum-annealed LaO${}_{0.5}$F${}_{0.5}$BiS${}_2$

S. Yadav, S. Delgado, O. O. Bernal +9

We report results of magnetization and ${}^{19}$F NMR measurements in the normal state of as-grown LaO${}_{0.5}$F${}_{0.5}$BiS${}_2$. The magnetization is dominated by a temperature-indepe…
