Quantum anomalous Hall effect has been observed in magnetically doped topological insulators. However, full quantization, up until now, is limited within the sub-1 K temperature regime, although the material's magnetic ordering temperature can go beyond 100 K. Here, we study the temperature limiting factors of the effect in Cr-doped (BiSb)<sub>2</sub>Te<sub>3</sub> systems using both transport and magneto-optical methods. By deliberate control of the thin-film thickness and doping profile, we re ...[more]
