Understanding the critical scaling behaviors of quantum phase transitions can provide profound physical implications. Here, the authors report temperature dependence of the derivative of longitudinal resistance at a magnetic-field induced quantum phase transition between the quantum anomalous Hall insulator to the axion insulator in magnetic topological insulator sandwich samples.
