      abstract     = {The quantum anomalous Hall effect1,2 is a fundamental
                      transport response of a topological insulator in zero
                      magnetic field. Its physical origin is a result of an
                      intrinsically inverted electronic band structure and
                      ferromagnetism3, and its most important manifestation is the
                      dissipationless flow of chiral charge currents at the edges
                      of the system4, a property that has the potential to
                      transform future quantum electronics5,6. Here, we report a
                      Berry-curvature-driven4,7 anomalous Hall regime at
                      temperatures of several Kelvin in the magnetic topological
                      bulk crystals in which Mn ions self-organize into a
                      period-ordered MnBi2Te4/Bi2Te3 superlattice. Robust
                      ferromagnetism of the MnBi2Te4 monolayers opens a surface
                      gap8,9,10, and when the Fermi level is tuned to be within
                      this gap, the anomalous Hall conductance reaches an e2/h
                      quantization plateau, which is a clear indication of chiral
                      transport through the edge states. The quantization in this
                      regime is not obstructed by the bulk conduction channels and
                      therefore should be present in a broad family of topological
                      magnets.},
