Carrier scattering by intercalated Fe spin ordering in 2H-NbS2 van der Waals gap

We have measured the electrical resistivity and the Hall coefficient of the metallic intercalation compounds FexNbS2 (0.159 < x < 0.325). The magnetic scattering by the spin fluctuation of Fe superstructure was observed in th e electrical resistivity. The anomalous Hall coefficient due to the asymmet ric carrier scattering changes its sign from positive to negative at the cr itical content x=1/4. These results indicate that the electronic properties of the system strongly depend on the spin ordering of the Fe ions in the v an der Waals gap.
