  We report on low-temperature electron transport properties of MnSb2Te4, 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 lnT-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 lnT-type upturn in the same temperature range,
such correction is absent in the anomalous Hall conductivity. Our work
demonstrates that MnSb2Te4 microflakes provide an ideal system to test the
theory of EEI correction to the anomalous Hall effect.
