Abstract We report on low-temperature electron transport properties of MnSb$_{2}$Te$_{4}$, a candidate of ferrimagnetic Weyl semimetal. Long-range magnetic order is manifested as a nearly square-shaped hysteresis loop in the anomalous Hall resistance, as well as sharp jumps in the magnetoresistance. At temperatures below 4 K, a ${\rm ln}T$-type upturn appears in the temperature dependence of longitudinal resistance, which can be attributed to the electron-electron interaction (EEI), since the weak localization can be excluded by the temperature dependence of magnetoresistance. Although the anomalous Hall resistance exhibits a similar ${\rm ln}T$-type upturn in the same temperature range, such correction is absent in the anomalous Hall conductivity. Our work demonstrates that MnSb$_{2}$Te$_{4}$ microflakes provide an ideal system to test the theory of EEI correction to the anomalous Hall effect.

B 64 104411 | | [32] | This approximation is valid because $R_{xx}$ is two orders of magnitude larger than $R_{\rm AH }$in MnSb$_{2}$Te$_{4}$. In this work, the AH conductivity $\sigma_{\mathrm{AH}}$ refers to the sheet conductance per square, and hence has a dimension of inverse resistance. It is convenient for discussing the physics at two dimensions. | | [33] | Altshuler B L and Aronov A G 1983 Solid State Commun. 46 429 |
