Anomalous Hall effect in ferromagnetic Weyl semimetal candidate Zr_1-xV_xCo_1.6Sn

We grew single crystals of vanadium-substituted, ferromagnetic Weyl semimetal candidate Zr_1-xV_xCo_1.6Sn from molten tin flux. These solid solutions all crystallize in a full Heusler structure (L2₁) while their Curie temperatures and magnetic moments are enhanced by V-substitution. Their resistivity gradually changes from bad-metal-like to semiconductor-like with increasing x while the anomalous Hall effect (AHE), which can be well fitted by Tian-Ye-Jin (TYJ) scaling,¹ is also enhanced. Moreover, we find an apparent electron-electron interaction (EEI) induced quantum correction in resistivity at low temperature. The anomalous Hall conductivity (AHC) dominated by the intrinsic term is not corrected.
