Abstract: The variation of the effective mass m * of carrier is often overlooked in experimental studies on quantum oscillations and Kohler's rule. Here, we report the magnetotransport properties of La3ScBi5 and reveal the changing m * in it. The temperature and magnetic field dependence of m * follows the power-law scaling behavior at low temperature and leads to the failure of conventional analysis, which should not be ignored. In the analysis of the thermal factor and Dingle plot of de Haas–van Alphen oscillation in La3ScBi5, satisfactory fitting results can be obtained after considering the correction of m *. We have also applied this method to Sr1− y Mn1− z Sb2, solving the remaining fitting problem in previous reports. Moreover, the magnetoresistance (MR) of La3ScBi5 has been found to violate Kohler's rule. Although the extended Kohler's rule is applicable to high-temperature MR data, it does not scale the low-temperature data well. We further modified the extended Kohler's rule by introducing m *, and subsequently scaled the low-temperature MR data well. Our study emphasizes the importance of considering the variation of m * in the analysis of quantum oscillations and Kohler's rule, and provides a method for extracting the temperature and magnetic field dependence of m * through quantum oscillations, which is very beneficial for the data analysis of other materials in the future.
