摘要：

We grew single crystals of vanadium-substituted, ferromagnetic Weyl semimetal candidate Zr1-xVxCo1.6Sn from molten tin flux. These solid solutions all crystallize in a full Heusler structure (L2(1)) while their Curie temperatures and magnetic moments are enhanced by V-substitution. Their resistivity gradually changes from bad-metal-like to semiconductor-like with increasingxwhile 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.
