Abstract: ${\mathrm{TiSe}}_{2}$ is a typical transition-metal dichalcogenide known for its charge-density-wave order. In this study, we report the observation of an unusual anisotropic negative magnetoresistance in exfoliated ${\mathrm{TiSe}}_{2}$ nanoflakes at low temperatures. Unlike the negative magnetoresistance reported in most other transition-metal dichalcogenides, our results cannot be explained by either the conventional two-dimensional weak localization effect or the Kondo effect. A comprehensive analysis of the data suggests that the observed anisotropic negative magnetoresistance in ${\mathrm{TiSe}}_{2}$ flakes is most likely caused by the three-dimensional weak localization effect.
