      abstract     = {Three-dimensional topological insulators (TIs) are a
                      material class which may enable robust topological quantum
                      computing by using so-called Majorana zero modes. Published
                      theoretical work predicts the Majorana state to exist in
                      magnetic topological insulators which exhibit the quantum
                      anomalous Hall effect (QAHE). We present magnetotransport
                      measurements of Cr-doped magnetic (Bi0.27Sb0.73)2Te3 which
                      partially show the QAHE. At 1.2 K, the uniformly Cr-doped
                      samples show a magnetic signature whose behaviour is probed
                      under gate influence. Based on these measurements, an
                      existing QAHE is ruled out. The results are compared to a
                      magnetic TI-heterostructure which shows the QAHE. The
                      temperature dependence of the effect is measured. In
                      addition, the magnetic energy gap is probed by a gate
                      dependent measurement. The QAHE is improved by current
                      adjustment.},
