Direct evidence of ferromagnetism in a quantum anomalous Hall system Wenbo Wang1, Yunbo Ou 2, Chang Liu2, Yayu Wang2,3, Ke He2,3, Qi-Kun Xue2,3 and Weida Wu 1* Quantum anomalous Hall (QAH) systems are of great fundamental interest and potential application because of their dissipationless conduction without the need for an external magnetic field1–9. The QAH effect has been realized in magnetically doped topological insulator thin films10–14. However, full quantization requires extremely low temperature (T
